Fluid Analysis of Wave Energy System Using Double Impeller Wheel

摘要

The storage of wave energy is abundant in our world,and how to gather and exploring wave energy for many offshore power supply purposes is focused widely.Shanghai Ocean University proposed a sort of double grades impeller wheel wave energy system for offshore small device power supplying.In this paper,the interval distance of two impellers is considered for the efficiency of gathering wave energy.With the help hand of virtue CFD software FLUENT,a patch of flow field simulations have been down for axial swirl machine,and pathline and statistics results are obtained.In which,some specific fluid theory,CFD mesh methods,and simulation boundary settings are introduced and involved.According to those results,the flow path and power index was discussed and analyzed.Then the most appropriate interval distance of two grades was selected.All work in the paper simplifies the optimization process for turbo-blade-like machine,which save both money and time for research and manufacture.And can also give reference and guidance for the same category projects in driven liquid turbo machine field.
