자유수면 아래에 위치한 기포의 거동에 대한 수치시뮬레이션

초록

This paper deals with the numerical simulation of the behavior of a single bubble rising under ths free surface. Desity function method for two phase flow simulation is adopted. A bubble of spherical shape positioned under the free surface is assumed at the initial stage.The differance according the fluid properties of surrounding medium is simulated. Numerical simulation results are depicted and explained with the time history of bubble shape.
