気泡関数要素安定化法を用いた気液二相流解析

抄録

An advanced VOF (volume of fluid) method with sophisticated interface evaluation is proposed for two-dimensional and three-dimensional two-phase flows on the incompressible viscous fluid. In the improved VOF method, the stabilized bubble function finite element method with numerical stability and acceptable accuracy is employed. The interface expression suited to the finite element analysis is derived to estimate the interface of the gas-liquid based on the digitizer method.
