Research on the Design Method of 3D Blade Profiles for Stator and Rotator of Turbodrill
In order to study the hydraulic performance of turbine 3D blade profile,a theoretical molding method for turbine 3D blade profile was proposed based on the equal circulation method,and a calculation method for the characteristic parameters of the turbine 3D blade profile was derived.Then,the ANSYS Fluent software was used to conduct numerical simulation on the turbine 3D blade profile and 2D blade profile of the same size,and analyze the hydraulic characteristics of them.The research results show that compared with 2D blade profile,the pressure drop of turbine 3D blade profile is reduced by about 50%,and the hydraulic efficiency is improved by a-bout 5%;the error between theoretical calculation and simulation results of 3D blade profile turbine torque is about 10%,within the allowable range of actual engineering.The research results provide a theoretical basis for the de-sign of turbine 3D blade profile.
