The applicability of vortex identification methods for complex vortex structures in axial turbine rotor passages被引量：11
《Journal of Hydrodynamics》2019年第4期700-707,共8页Yu-fan Wang Wei-hao Zhang Xia Cao Hong-kai Yang 
Project supported by the National Natural Science Foundation of China (Grant No. 51406003);This work is accomplished by using the code RortexUTA and the code Omega-LiutexUTA which are released by Chaoqun Liu at University of Texas at Arlington.
The complex vortex structures in the flow around turbine rotor passages, with weak or strong, large or small vortices, interacting with each other, often generate most of aerodynamic loss in turbomachines. Therefore, ...
