Optimization of a Real Scale Shrouded Wind Turbine Using 3D CFD Analysis

Abstract


This study aims to simulate and compare three different wind turbines; flanged shrouded wind turbine, shrouded turbine with no flange, and bared wind machine. The 3D models of all of the mentioned turbines are made. Velocity is the most effective parameter when studying output power. So in the present work, velocity is improved implementing different geometries. The outcomes indicate that among the three types, the maximum output power is made by the turbine, including a shroud and also an attached flange. The benefits of flanged shrouded wind turbines are discussed. The results report that when comparing with that of the bared wind turbine, output power rose by 106% with the use of a simple shroud and by approximately 137% with the use of a flange attached to the shroud. This improvement is the result of the occurrence of the low-pressure region at the shroud outlet, which is enhanced the presence of the flange in the best model. Low pressure leads to higher mass flow and consequently, higher power generation.
