Повний текст джерелаThe impact of the viscous and vortex forces in the context of floating wave energy devices has been studied in this work. At present the state of the art tools to assess the efficiency of the WECs (Wave Energy Converters) comprise the BEM (boundary element method) codes based on the potential linear approach whereas CFD (computational fluid dynamics) is still considered to be computationally expensive. However the former has its limits regarding linearity restrictions and hence needs further inspections and improvements. A possibility for improvement is to account for viscous damping via additional Morison-like quadratic damping term. The intensity of this additional damping term depends on a coefficient which needs to be estimated prior to the calculations. One can interpolate this coefficient from the many previously published experimental results or imagine using CFD. In this study, the applicability of the latter option is investigated for WEC application. Two generic devices such as a heaving cylinder with sharp corners and a surging flap type WEC are considered. CFD computations of the forces on the buoy in an oscillatory flow are performed. This CFD-force is then fitted by the Morison’s equation using least square approach, which gives estimation of the viscous damping coefficient. This coefficient is implemented in the equation of motion of the WEC. The energy absorption with and without taking into account the viscous damping is then derived, which shows the importance of its appropriate modelling
Vallet, Alexandra. "Hydrodynamic modelling of the shock ignition scheme for inertial confinement fusion." Thesis, Bordeaux, 2014. http://www.theses.fr/2014BORD0214/document.
Повний текст джерелаThe shock ignition concept in inertial confinement fusion uses an intense power spike at the end of an assembly laser pulse. the key feature of shock ignition are the generation of a high ablation pressure, the shock pressure amplification by at least a factor of a hundred in the cold fuel shell and the shock coupling to the hot-spot. in this theses, new semi-analytical hydrodynamic models are developed to describe the ignitor shock from its generation up to the moment of fuel ignition. A model is developed to describe a spherical concerging shock wave in a pre-heated hotspot. The self-similar solution developed by Guderley is perturbed over the shock Mach number Ms >>1. The first order correction accounts for the effects of the shock strength. An analytical ignition criterion is defined in terms of the shock strength ans th hot-spot areal density. The ignition threshold is higher when the initial Mach number of the shock is lower. A minimal shock pressure of 20 Gbar is needed when it enters the hot-spot. The shock dynamics in the imploding shell is the analyzed. The shock is propagating into a non inertial medium with a high radial pressure gradient and an averall pressure increase with time. The collision with a returning shock coming from the assembly phase enhances further the ignitor shock pressure. The analytica theory allows to des cribe the shock pressure and strength evolution in a typical shock ignition implosion. It is demonstrated that, in the case of the HiPER target design, a generation shock pressure near the ablation zone on the order of 300-400 Mbar is needed. An analysis of experiments on the strong shock generation performed on the OMEGA laser facility is presented. It is sown that a shock presssure close to 300 Mbar near the ablation zone has been reached with an absorbed laser intensity up to 2 x 10(15) W:cm-2 and a laser wavelength of 351 nm. This value is two times higher than the one expected from collisional laser absorption only. That significant pressure enhancement is explained by contribution of hot-electrons generated by non-linear laser/plasma interaction in the corona. The proposed analytical models allow to optimize the shock ignition scheme, including the inuence of the implosion parameters. Analytical, numerical and experimental results are mutualy consistent
Angelotti, de ponte rodrigues Natalia. "Open water swimming : Monitoring and hydrodynamic modelling for sanitary conditions assessment." Electronic Thesis or Diss., Marne-la-vallée, ENPC, 2023. http://www.theses.fr/2023ENPC0046.
Повний текст джерелаSwimming in open water has become very popular, particularly in urban areas where summer heatwaves are increasingly frequent. To control sanitary risks, the monitoring of indicators of pathogenic microorganisms, namely faecal indicator bacteria (FIB), such as E. coli is required. Reference laboratory methods take at least 24h to provide results.For opening a bathing area to the public, FIB concentrations must meet the regulatory limits. In watercourses, this condition can be estimated from measurements at an upstream point, defined to take into account the transfer time to the bathing area and the response time of the FIB measurement.The transfer time is affected by flowrate and thermal stratification. Variations in current velocity can be computed using hydrodynamic models, which are also useful to estimate the FIB spatiotemporal distributionIn order to propose a system for monitoring and forecasting the microbiological quality of bathing areas, two research lines have been developed: (1) the implementation of a 3D hydrodynamic model to compute the velocity field and the water temperature and (2) the definition of a FIB proxy for faster microbiological water quality assessment.The specific objectives of the PhD thesis are as follows:- To implement the 3D hydrodynamic model TELEMAC-3D, coupled with the WAQTEL thermal module;- To design and install a monitoring system to obtain field data that can be used for input and validation of the hydrodynamic model;- To investigate the influence of thermal stratification on the spatiotemporal distribution of faecal contamination;- To identify a fast-measuring indicator of FIB.The study site, La Villette basin, is located in Paris (France). It consists of a canal upstream (25m wide, 800m long), and a basin downstream (70m wide, 700m long, 3m deep). The average discharge is around 2.1m³.s-1.The installed fully autonomous monitoring system consists of two monitoring points located: (1) 1000m upstream of the bathing area and (2) downstream, close to the bathing area. At both sites, water temperature is measured at three depths, and electrical conductivity at mid-depth, with a 10 min time step.From spring to mid-autumn, the data showed a daily thermal stratification of the water column, breaking up at night. Conductivity data allowed to estimate the transfer time between both monitoring points. The values varied from 6h30 to more than 24h.To obtain real-time information on FIB level, the relationship between FIB and the fluorescence of dissolved organic matter (FDOM) was investigated. Fluorescence spectroscopy combined with PARAFAC modelling was used to characterize DOM and microbiological activity in five watercourses in the Paris metropolitan region. The results showed a higher presence of a protein-like component in samples with higher microbial contamination. A relationship was established between this component and FIB.For a short-term (3 days) FIB level forecast, a relationship between FIB and hydro-meteorological data (discharge, rainfall and dry weather duration) was investigated. In La Villette basin, a relationship between E. coli and the precipitation measured upstream, between one and three days before the day of interest, was found.The in-situ measured values were used as model input and for validation. The FIB concentration was derived from FDOM data and from hydro-meteorological data using the established relationships.The results of the 3D hydro-microbiological model were compared to field data. The observed alternation of thermal stratification and mixing was correctly reproduced. Its effect on E. coli spatial distribution was highlighted. The conductivity variation was well simulated. The transfer time between the two measuring points was correctly estimated and can be applied to other passive tracers.This work highlights the relevance of a 3D hydrodynamic model for assessing contaminant transport and sanitary conditions in a river area of interest
