On sharp-interface level-set method for heat and/or mass transfer induced Stefan problem

摘要: A detailed sharp interface level set method (SI-LSM) based CFD development methodology as well its implementation and application to the various types of Stefan problem is not found reported here. The code-validation are presented in-detail for heat and/or mass transfer induced flow, 2D Cartesian axi-symmetric coordinate system Dirichlet jump boundary conditions at interface. For BC, a higher order extrapolation – computation ghost fluid value across Whereas, generic finite volume discretized equation proposed consisting additional source term modification in diffusion coefficient control-volumes adjoining An excellent agreement between present published results shown separately flow problems by (melting solidification), (isothermal evaporation) (non-isothermal evaporation). Finally, performance study demonstrating superior compared diffused method. also two different methods normal gradient interface, with regard numerical oscillations results.The work involving localized two-phase domain will be extremely useful developer on multi-phase flow.
