The air-water bubbly flow around a hydrofoil is simulated with the vortex method proposed by the authors in a prior paper. A hydrofoil of NACA4412 with a chord length 100mm is mounted at the angle of attack of 10 degree in an air- water bubbly flow. The Reynolds number is 2.5×10^5, the bubble diameter is 1 mm, and the volumetric flow ratio of bubble to whole fluid is 0.048. The simulation demonstrates that the two-phase flow features around the hydrofoil are successfully captured and that the vortex method is indeed applicable to the bubbly flow analysis around a hydrofoil.
