Hydrokinetic propeller turbines. How many blades?
TypeArticles dans des revues avec comité de lecture
A design study of propeller hydrokinetic turbines is presented. The main objective is to evaluate the optimized geometry for horizontal axis hydrokinetic turbines, take into account the runner design with a different number of blades. The optimized blade geometry is determined by the Glauert theory for axial free flow turbines (hydrokinetic and wind turbines). The performance of the different blades is evaluated in the entire range of operating conditions, using Blade Element Momentum Theory (BEMT). Computational Fluid Dynamics (CFD) computations were also carried out to evaluate the detailed features of the fluid flow

CHABI, Fatiha; CHAMPMARTIN, Stéphane; SARRAF, Christophe; NOGUERA, Ricardo (Elsevier, 2015)We evaluate here three hemodynamic models used for the numerical simulation of bare and stented artery flows. We focus on two flow features responsible for intra-stent restenosis: the wall shear stress and the re-circulation ...
