In this study, two-dimensional flow analysis around cross-section of the surface piercing propeller with a linear profile trailing edge is studied in different Weber numbers.Due to collision of the two-dimensional cross section with surface water, aeration zone is cookies portable dab rig created on the suction side that is heavily impact on the results.The ventilation pattern is a function of the geometrical parameters.In this article, in particular, the effect of surface tension and the Weber number have been investigated.According to the obtained results at low Weber numbers, the surface tension effect increases the amount of water surface uplift, and water droplets are visible in the trailing edge of blade gelish rosita section.

At Weber numbers higher than critical Weber number, surface tension effect will only cause loss of fluid droplets in the inlet region.
