作者（2019）在《Effects of outer rim of rotors on performance of turbodrills》一文中研究指出：Two turbine rotors with outer rim and without outer rim were designed to analyze the influence 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 software. The 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 show that the torque,pressure drop and hydraulic efficiency of the turbine rotor with outer rim are greater than that of the turbine rotor without outer rim. By comparing the turbine rotor with outer rim and without outer rim,its torque increases 20. 1%,pressure drop increases 8.7% and hydraulic efficiency increases 10.4% at the maximum efficiency point.

Abstract
Two turbine rotors with outer rim and without outer rim were designed to analyze the influence 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 software. The 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 show that the torque,pressure drop and hydraulic efficiency of the turbine rotor with outer rim are greater than that of the turbine rotor without outer rim. By comparing the turbine rotor with outer rim and without outer rim,its torque increases 20. 1%,pressure drop increases 8.7% and hydraulic efficiency increases 10.4% at the maximum efficiency point. The related research is of guiding significance to further optimization of turbine rotor structure.
