균일유동장에서의 기포의 거동에 대한 수치시뮬레이션

초록

Present research is a basic study about the air bubble method for the reduction of ship resistance. Therefore, the motion of air bubble in uniform flow filed is numerically simulated in this study. The results are expected to be applied to the simulation of the motion of air bubble around ship and the reduction of ship resistance. For the governing equations of the fluid flows, the Navier,-stokes equations and the continuity equation are employed.And then a finite difference method is used for the differentiation of governing equations, and Density-function method is adopted for the definition of the interaction phenomena of bubbles by using the present numerical scheme. Finally, the second purpose is the analysis of the motion of bubble in uniform flow field.
