Savonius型转轮三角阵列减流性能研究
Research on the flow reduction performance of a Savonius hydrokinetic rotor with a triangular array
摘要
Abstract
To assist in the flow reduction and protection engineering of marine pastures,the flow reduction performance of Savonius hydrokinetic rotor array units is studied.A numerical model is established for the wake flow field of the Savonius hydrokinetic rotor triangular array,and its accuracy is verified through water tank experiments.Based on a reliable numerical model,the mechanism of vortex reduction is explored in the wake of the hydrokinetic rotor array unit,and the influence of the structural parameters LX and LY of the triangular array,as well as the dynamic parameters TSR,initial velocity,and rotation direction on the overall flow reduction performance,are studied.The results indicate that the vortices generated by downstream rotors exhibit an asymmetric distribution,and rotors generating additional vortices show better flow reduction effects.In addition,the best flow reduction performance is achieved when LX is 3D and LY is 2D.Finally,the comparison shows that the flow reduction effect is better when the blade tip speed ratio is between 0.9 and 1.1.When the downstream rotor is distributed symmetrically,the flow reduction effect differs considerably as the upstream rotor changes its rotation direction.关键词
