Full textParticle separation is an important requirement in chemistry, physics, biology, medical domains and biotechnology. For instance, the conventional biomass harvesting which is one of the key steps in production of biofuels from non-feed stocks such as microalgae and cyanobacteria, is a complex and costly process (20-30% of total cost) due to the small size and low-density difference of the photosynthesis microorganisms and their growth media. Thus, novel low-cost techniques are required to substitute or improve the downstream separation process. While a variety of active and passive techniques have been proposed for the separation process in steady flows, pulsatile flow has received much less attention. The purpose of this study is to determine the effects of flow pulsation on the separation of particles in a double Y-microchannel. Only one of the two entering flows contains the particles and the separation efficiency is defined as the ratio of the particles escaping from the opposite outlet to the total number of particles. Dead and motile cells of Chlamydomonas reinhardtii are used as passive and active particles, respectively. Both experiments and simulations are carried out for each part of the study. The key results can be summarized as follows: For passive particles: - When the inlet flows are in a steady regime, the only parameter that allows controlling the particle separation/distribution is the ratio between the flow rates at the inlets. The separation efficiency increases with increasing this ratio. To approach the maximum efficiency (0.5), this ratio should be more than 20, which is not always practical. - When the inlet flows are pulsating with a phase shift, adjusting the phase shift between the inlet flows can control the separation efficiency. - When 0.5 < pulsation amplitude < 2 and 1 s < pulsation period < 10 s, the separation efficiency increases with the phase shift such that phi = 180° gives the highest efficiency. A similar trend can be observed for higher values of amplitude (like beta = 5) only if the pulsation period is small enough. For active particles: - Active particles (motile cells) do not obey the control protocol imposed at the inlet of the system. The separation efficiency remains around 0.5 implying that active particles choose their exit from the microchannel randomly. Therefore, pulsation (alone) shows no advantage for separation of the active particles compared to a steady flow. - However, when the phototactic behavior of the algae is coupled with pulsatile flow features, the advantage of pulsation becomes clear. In the presence of light stimulation, the separation efficiency increases to 65% and 75% in steady and pulsatile flows respectively. Although the experiments are conducted on the well-known model alga, Chlamydomonas reinhardtii, a simplified numerical simulation demonstrated that the idea can be extended to any other active particle stimulated by an attractive or repulsive external field. Thus, the potential applications of pulsatile flow can go beyond algae harvesting to control and improve separation, selection or accumulation processes without using any mechanical component or chemical substance

Full textThe thesis studies the peristaltic flow of fluid in a channel with the specified pressure wave at the boundary. The law of wall’s coordinate variation isn’t determined a priori. It is found from the initially definite law of pressure-variation on the wall. This way is based on the fact that some hollow organs change diameter under the signals of baroreceptors (sensors that detects the pressure). We studied the effects of various parameters on flow rate and structure of flow. Besides we studied the influence of vibration on the peristaltic flow under long wave approximation. The paper also considers the influence of the wall transverse pulsation on the fluid transport under the pressure drop. This problem arises in defining the liquid viscosity by squeezing flow viscometry. The same problems occur in analyzing different biological systems, including the lubricant movement in joints or in the microvessels of working muscles. The influence of sound on the interaction of a solid particle and a gas bubble in fluid is studied as well

Full textO detector ultra-sónico de fluxo sanguíneo usa o efeito Doppler para estimar de forma não invasiva a velocidade do sangue na circulação. Tem sido bastante usado nas últimas quatro décadas para detectar a presença de estenoses.O desenvolvimento de novas técnicas de processamento do sinal Doppler necessita de sinais de teste cujas características sejam conhecidas ou possam ser medidas com precisão. Isto é difícil de obter com sinais Doppler medidos in vivo devido à elevada variação do fluxo sanguíneo de pessoa para pessoa e também com o estado fisiológico da pessoa no momento da medida, por exemplo a tensão arterial influencia significativamente o fluxo sanguíneo. Um modelo para gerar sinais Doppler simulados cujas características sejam controláveis e/ou mensuráveis é uma ferramenta bastante útil, pois permite que as novas técnicas de processamento do sinal Doppler sejam testadas em condições controladas. Permite, também, estudar o efeito de vários factores que afectam o espectro do sinal Doppler. Habitualmente o efeito individual dos vários factores não pode ser identificado quando são usados sinais medidos in vivo.Neste trabalho foi desenvolvido um modelo para gerar sinais Doppler ultra-sónicos simulados. O modelo contém dois sub-modelos, um para o fluxo sanguíneo nos membros inferiores de um ser humano e outro para gerar os sinais simulados a partir do campo de velocidades do sangue e das características do instrumento.O fluxo sanguíneo nos membros inferiores foi simulado com um análogo eléctrico para a rede vascular dos membros inferiores. Cada artéria foi simulada por uma linha de transmissão com perdas e as redes vasculares periféricas por um circuito Windkessel com três elementos. O circuito eléctrico foi implementado com o simulador de circuitos SPICE.Para simular a interacção entre os glóbulos vermelhos e o campo de ultra-sons o vaso sanguíneo foi dividido em pequenos volumes elementares. As contribuições dos volumes elementares foram todas somadas para gerar o sinal Doppler simulado. O modelo fez algumas aproximações como sejam, por exemplo, considerar o fluxo sanguíneo laminar e sem rotação.As características dos sinais gerados pelo modelo são bastante parecidas com as esperadas para o sinal Doppler real. O modelo desenvolvido foi usado para estudar a influência que a aceleração sanguínea, o tamanho do volume de amostragem e a duração da janela de amostragem têm na largura de banda eficaz do espectro do sinal Doppler. Foi deduzida uma fórmula que estima a largura de banda eficaz a partir das contribuições individuais do alargamento espectral devido à não estacionaridade, do alargamento espectral intrínseco, do alargamento espectral devido à duração da janela de amostragem e ainda da gama das velocidades que passam pelo volume de amostragem. Foram, ainda, deduzidas expressões em forma fechada para o espectro de potência do sinal Doppler devido unicamente à gama de velocidades que atravessam um volume de amostragem com forma Gaussiana colocado num perfil de velocidades com forma exponêncial. Foram, também, obtidas expressões para a largura de banda eficaz no caso especial do volume de amostragem Gaussiano ter simetria esférica e estar colocado no centro do vaso sanguíneo.

Resumo: Introdução: Dentre os equipamentos utilizados em circulação extracorpórea, as bombas de roletes têm grande importância, com modelos disponíveis de vários fabricantes. O ajuste dos roletes é um fator importante nas taxas de hemólise e o potencial hemolítico difere em cada um deles. Pesquisadores nem sempre abordam detalhes sobre os perfis do leito rígido supondo que as formas padronizadas de ajuste garantem valores iguais e comparáveis para todos os modelos de bombas de roletes. Dispomos principalmente de dois métodos para o ajuste de bombas de roletes e nenhum deles considera as características de impulsão do fluido, definida pelo perfil do leito rígido. Objetivo: O objetivo desse trabalho é analisar o perfil hidrodinâmico de três diferentes modelos de bombas de roletes comercializados no Brasil e sua influência no fluxo e refluxo. Materiais e Métodos: Foram utilizados tubos de silicone de 9,5x1,6; 9,5x2,4; 13x2,4 mm de diâmetro de dois fornecedores diferentes. Os testes foram realizados em solução fisiológica e solução análoga ao sangue. O perfil hidrodinâmico de três bombas de roletes foi realizado por medidas de velocidade de queda e calibração dinâmica. Foi investigada a variação das medidas de velocidade de queda com o tempo e testes de compressão em equipamento servo-hidráulico. Os refluxos foram visualizados em aspirador de sangue e reservatório de cardiotomia com medidas simultâneas. Resultados: Os perfis hidrodinâmicos apresentaram diferenças em suas variâncias para medidas de velocidade de queda (P<0,01) e calibração dinâmica (P<0,0001). A tensão residual nos tubos de silicone ocasionou redução nas medidas de velocidade de queda com o tempo (P<0,0002) e foram confirmadas pelos testes de compressão (P<0,0001). Conclusão: Os ajustes realizados pelos métodos de velocidade de queda e calibração dinâmica são dependentes da forma do leito rígido. Comparações envolvendo bombas de roletes devem ser feitas com cautela. A tensão residual em tubos de silicone compromete a repetitividade dos ajustes feitos pelo método de velocidade de queda.
Abstract: Introduction: Among the equipment used in cardiopulmonary bypass, roller pumps have great importance, with models available from several manufacturers. The roller adjustment is an important factor in the rates of hemolysis and the hemolytic potential differs in adjustment. Researchers do not always address details on the profiles of the raceway accepting that the forms of standardized settings ensure equal and comparable values for all models of roller pumps. There are two methods for setting roller pumps and none considers the dynamic characteristics of the fluid, defined by the profile of the raceway. Objective: The aim of this study is to analyze the hydrodynamic profile of three different models of roller pumps commercialized in Brazil and its influence on the flow and back flow. Materials and methods: We used silicone tubes of 9.5x1.6, 9.5 x2.4 and 13x2.4 mm in diameter from two different suppliers. The tests were performed in saline and solution analogous to blood. The hydrodynamic profile in three roller pumps was achieved by measurements of drop rate and dynamic calibration. The drop rate variations were investigated in silicone tubes by measurements of drop rate and the compression tests in servo-hydraulic equipment. Retrograde flows were viewed in blood aspirator and cardiotomy reservoir. Results: The hydrodynamic profiles showed differences in their variances for measurements of drop rate (P <0.01) and dynamic calibration (P <0.0001). The residual stress in the silicone tubes caused reduction in drop rate with time (P<0.0002) and were confirmed by compression tests (P <0.0001). Conclusion: The adjustments made by the methods of drop rate and dynamic calibration are dependent on the raceway profile. Comparisons involving roller pumps must be made with caution. The residual stress in the silicone tubes compromises repeatability of adjustments made by the drop rate method.

Full textNon-pulsatile and pulsatile flow in bent pipes and radial turbine has been assessed with numerical simulations. The flow field in a single bent pipe has been computed with different turbulence modelling approaches. A comparison with measured data shows that Implicit Large Eddy Simulation (ILES) gives the best agreement in terms of mean flow quantities. All computations with the different turbulence models qualitatively capture the so called Dean vortices. The Dean vortices are a pair of counter-rotating vortices that are created in the bend, due to inertial effects in combination with a radial pressure gradient. The pulsatile flow in a double bent pipe has also been considered. In the first bend, the Dean vortices are formed and in the second bend a swirling motion is created, which will together with the Dean vortices create a complex flow field downstream of the second bend. The strength of these structures will vary with the amplitude of the axial flow. For pulsatile flow, a phase shift between the velocity and the pressure occurs and the phase shift is not constant during the pulse depending on the balance between the different terms in the Navier- Stokes equations.
The performance of a radial turbocharger turbine working under both non-pulsatile and pulsatile flow conditions has also been investigated by using ILES. To assess the effect of pulsatile inflow conditions on the turbine performance, three different cases have been considered with different frequencies and amplitude of the mass flow pulse and different rotational speeds of the turbine wheel. The results show that the turbine cannot be treated as being quasi-stationary; for example, the shaft power varies with varying frequency of the pulses for the same amplitude of mass flow. The pulsatile flow also implies that the incidence angle of the flow into the turbine wheel varies during the pulse. For the worst case, the relative incidence angle varies from approximately −80° to +60°. A phase shift between the pressure and the mass flow at the inlet and the shaft torque also occurs. This phase shift increases with increasing frequency, which affects the accuracy of the results from 1-D models based on turbine maps measured under non-pulsatile conditions.
For a turbocharger working under internal combustion engine conditions, the flow into the turbine is pulsatile and there are also unsteady secondary flow components, depending on the geometry of the exhaust manifold situated upstream of the turbine. Therefore, the effects of different perturbations at the inflow conditions on the turbine performance have been assessed. For the different cases both turbulent fluctuations and different secondary flow structures are added to the inlet velocity. The results show that a non-disturbed inlet flow gives the best performance, while an inflow condition with a certain large scale eddy in combination with turbulence has the largest negative effect on the shaft power output.

Full textFollowing vascular injury, blood platelets adhere, become activated and aggregate to form a hemostatic plug which stops the bleeding. In a pathological context, platelet aggregation can also lead to the formation of an occlusive thrombus, responsible for lifethreatening ischemic events. Current antiplatelet drugs targeting platelet activation and aggregation, have a recognized efficacy, but also present some limitations including the recurrence of ischemic events and the risk of bleeding. The aim of my thesis was to explore the importance of the initial step of platelet adhesion to subendothelial proteins and the role of pulsatile blood flow in platelet aggregation. I provided evidence that RAM.1 an antibody directed against GPIbβ, reduces GPIb signaling and thrombus formation without affecting hemostasis. My work also showed that fibrillar cellular fibronectin is a thrombogenic surface which supports efficient adhesion, activation, aggregation and procoagulant activity of platelets. Finally, I observed that the pulsatility of the blood flow has an inverse role in the growth of thrombi in physiological and pathological settings. In conclusion, this work highlights the importance of initial stages of platelet adhesion and of the blood flow pulsatility in platelet aggregation
