Study on tip leakage vortex in an axial flow pump based on modified shear stress transport k-ω turbulence model

The tip leakage vortex structure and trajectory in an axial flow pump were investigated numerically and experimentally based on the modified shear stress transport k-ω turbulence model. Numerical results were compared with the experimental leakage vortex trajectories, and a good agreement w...
