A new vortex identification method (Liu et al. 2016) was proposed to represent the rotation relative strength and capture and visualize the vortices in our previous study. The basic idea of the 惟 method is that a ratio of the vorticity squared over the summation of the vorticity squared and...

Furthermore, we can also observe the occurrence of a negative side effect, that is, a strong vortex in the lower part of the propeller disk. From the methodological standpoint this is not representing a problem, since the Pareto front has been correctly identified, but practically this is ...
