비압축성 다상유동 해석을 위한 VOF가 적용된 Fractional Step 기법

초록

We present a fractional step method combined with volume-of-fluid method for analysis of incompressible multiphase flow. The boundary between the fluids is constructed by the least squares volume-of-fluid interface reconstruction algorithm and advected by the velocity using the operator split advection algorithm. For verifying our numerical methodology, the present results of Rayleigh-Taylor instability problem are compared with those of other authors’.
