摘要 Two turbine rotors with outer rim and without outer rim were designed to analyze the influe-nce of outer rim of rotors on the performance of a turbodrill. Two 3D models of the turbine rotor with different structures were established by SolidWorks. Numerical simulation analysis of the turbine with different rotor structures was carried out based on software of fluent and then the performance of them at different rotating speeds was obtained. The results showed that the torque, pressure drop and hydraulic efficiency of the turbine rotor with outer rim were greater than those of the turbine rotor without outer rim. By comparing the turbine rotor with outer rim with that without outer rim, its torque increased 20.1%, pressure drop increased 8.7% and hydraulic efficiency increased 10.4% at the maximum efficiency point. The related research is of guiding significance to further optimization of turbine rotor structure.
