Numerical simulation of effects of the gap size on the tip leakage vortex around a NACA0009 hydrofoil

摘要：

　　Tip leakage flow around a NACA0009 hydrofoil at a wide range of gap sizes was predicted using the shear-stress transport (SST) turbulence model with a high-quality structured mesh, with the objective of investigating the effects of the gap size on the vortex core size, vortex strength and vortex position and of providing some useful information for controlling the tip leakage vortex cavitation.The numerical results show that the TLV has a more compact structure and a stronger strength for the larger gap sizes than that for the smaller gap sizes, and that the distance between the vortex trajectory and the hydrofoil is decreasing with increasing gap size.
