A level set method for analysis of film boiling on an immersed solid surface

초록

A numerical method is presented for simulating film boiling on an immersed ( or irregularly shaped) solid surface. The level set formulation for tracking the phase interfaces is modified to include the effect of phase change at the liquid-vapor interface and to treat the no-slip condition at the fluid-solid interface. The boundary or matching conditions at the phase interfaces are accurately imposed by incorporating the ghost fluid approach based on a sharp-interface representation. The numerical method is tested through computations of bubble rise in a stationary liquid, single-phase fluid flow past a circular cylinder, and film boiling on a horizontal cylinder.
