Повний текст джерелаBased on the equations of energy and momentum conservation, a model was formulated to predict the air flow performance of perforated ventilation ducts and to evaluate the outlet discharge angle and the duct regain coefficients without evaluating frictional losses. The basic assumptions of the model were validated by experimentally proving the equivalence of the friction losses expressed in the 2 cited equations. When compared to experimental results measured from four wooden perforated ventilation ducts with aperture ratios of 0.5, 1.0, 1.5, and 2.0, the model predicted the outlet air flow along the full length of perforated duct operated under turbulent flow conditions with a maximum error of 9%. The regain coefficient and the energy correction factor were equal to one, and the value of the discharge coefficient remained constant at 0.65, along the full length of the perforated duct. The outlet air jet discharge angle varied along the entire duct length, and was not influenced by friction losses for turbulent flow.
Assuming a common effective outlet area, the model was extended to match the performance of the fan and the perforated duct and to determine their balance operating point.

Повний текст джерелаThis study concerns the identification of dynamic models for performance evaluation and energy diagnosis of existing buildings. The work of this PhD takes place in a context of energy conservation and energy efficiency which are of essential interest today. We are dealing with occupied office buildings but relatively well instrumented. We have hourly measurements of outdoor temperature, solar radiation, heating power, electrical power and indoor air temperature. The aim is to propose a methodological approach to quantify the energy performance of building envelope from the available data, on the one hand, and to recommend ways to improve them, on the other. Major steps of the process evaluation / diagnosis given for the most fits with those of a standard procedure of identification: a) preliminary analysis of available data, b) choice of mathematical structures for well describing the building behavior c) model estimation and validation, and operation of the model for evaluation and diagnosis. With the results obtained by a first approach "black box" we make a tentative of detailed diagnosis based on physical building model ("white box")

Resumo: A abordagem tradicional da estimativa da área no procedimento de síntese de redes de trocadores de calor exige a escolha de um conjunto típico de coeficientes de transferência de calor. Uma vez obtida a topologia da rede de trocadores de calor, o projeto detalhado dos trocadores pode exigir a consideração de restrições nas quedas da pressão disponíveis, alterando os valores dos coeficientes de transferência de calor utilizados inicialmente na avaliação da rede e invalidando a otimização econômica da mesma. Com isso tem-se um aumento nos custos de projeto tanto na parte construtiva como na forma de bombas e/ou compressores do processo. Esta dissertação tem como finalidade elaborar uma nova abordagem que possibilite estimar a área de troca térmica a partir de uma relação entre quedas de pressão e coeficientes de transferência de calor no lado do casco e dos tubos. Assim, partindo das quedas de pressão permitidas das correntes pode-se estimar a área e os coeficientes de transferência de calor de um trocador de calor, munido de dados de processo como carga térmica, temperaturas, propriedades físicas e quedas de pressão no lado do casco e dos tubos, e possibilitando uma análise econômica mais correta da rede de trocadores de calor. Os métodos já disponíveis para esta finalidade possuem limitações uma vez que são baseados no método de Kern, que inclui severas simplificações no seu modelo, e o de Bell, que utiliza equações empíricas dependentes de aspectos geométricos. O procedimento de análise de trocadores de calor tipo casco e tubos de Wills & Johnston, utilizado neste trabalho, é uma alternativa bastante viável para este tipo de problema por ser considerado teoricamente mais preciso, baseando-se em equações hidráulicas para o cálculo da queda de pressão no lado do casco considerando os diversos caminhos do fluido no interior do casco
Abstract: In the traditional approach of heat exchanger network synthesis the procedure for area targeting requires de choice of a set of typical heat transfer coefficients. After the heat exchanger network structure has been defined the individual exchangers are design. However, due to pressure drop restrictions the final heat exchanger design might require heat transfer coefficients that are very different from the one originally chosen, leading to increased exchanger area and increased capital cost. This work aims to develop a new that allows the estimate of a correct set of heat transfer coefficients and exchanger area based on available pressure drops. The propose procedure allows for the estimate of heat transfer coefficients and area based on the available pressure drops. Methods already available for this purpose show limitations: the method of Kern includes severe simplifications while the method of Bell uses empirical equations dependent on geometric aspects. The method of Wills & Johnston, used in the present work, is a very feasible alternative for this type of problem as it is based on the pressure drop of the different fluid paths inside the shell side of the exchanger

Повний текст джерелаThroughout this work, the main objective is to validate the relevance of construction and use of geometric or parametric 3D models BIM or hBlM-oriented for numerical analyzes. These include structural studies in the case of historic buildings, as well as planning for restoration work, energy renovation and rehabilitation. Complementary data mining and use of point clouds for the detection, segmentation and extraction of geometric features have also been integrated into the work and proposed methodology. The process of data processing, geometric or parametric modeling and their exploitation, proposed in this work, contributes to improve and understand better the constraints and stakes of the different configurations and conditions related to the case studies and the specific constraints specific to the types of constructions. The contributions proposed for the different geometric and parametric modeling methods from point clouds are addressed by the construction of geometric models BIM or hBlM-oriented. Similarly, the process of surface detection, extraction of data and elements from point clouds are presented. The application of these modeling methods is systematically illustrated by different case studies, all of whose relative work has been carried out within the framework of this thesis. The goal is therefore to demonstrate the interest and relevance of these numerical methods according to the context, needs and studies envisaged, for example with the spire of the Senlis cathedral (Oise) and the Hermitage site (Oise). Numerical analyzes with finite element method are used to validate the relevance of these approaches

Повний текст джерелаSleeping scheduling is another approach to save energy consumption for sensor networks. The basic idea is to schedule the duty-cycles of sensor nodes such that off-duty sensors are turned off as long as the network functionality can be maintained by working nodes. For applications whereby coordination of sleeping among sensors is not possible or inconvenient, random sleeping is the only option. We present the Asynchronous Random Sleeping (ARS) scheme whereby sensors (i) do not need to synchronize with each other, and (ii) do not need to coordinate their wakeup patterns. The stationary coverage probability and the expected coverage periods for ARS are derived. For surveillance application, we derive in addition the detection probability and detection delay distribution. We find that the expected detection delay of asynchronous random sleeping is smaller than that of the synchronous random sleeping.
This thesis is focused on the design and analysis of energy conservation methods for wireless sensor networks (WSNs). Unlike traditional wireless networks, sensor nodes in WSNs are collaborating towards a common mission. The failure of some sensor nodes may cause significant topological changes and loss of information at the target region. Therefore, network lifetime is the primary objective for designing energy conservation solutions for WSNs.
We address the energy conservation problem from the aspects of maximum lifetime routing, data aggregation and sleeping scheduling. We first propose a data aggregated maximum lifetime routing scheme for wireless sensor networks. We adopt a data aggregation model that decouples the routing of local data and transit data. The objective is to jointly optimize data aggregation and routing so that the network lifetime can be maximized. A recursive smoothing method is adopted to overcome the nondifferentiability of the objective function. We derive the necessary and sufficient conditions for achieving the optimality of the smoothing function and design a distributed gradient algorithm accordingly. We show that the proposed scheme can significantly reduce the data traffic and improve the network lifetime. The distributed algorithm can converge to the optimal value efficiently under all network configurations.
