Abstract

A sharp interface level set method (SI-LSM) based computational multi-fluid dynamics (CMFD) methodology presented earlier by Shaikh et al. [1] for 2D is extended here for 3D Stefan problem of various types. The code-validation is presented in-detail for heat transfer induced Stefan flow with Dirichlet boundary conditions at the interface. For the Dirichlet boundary condition, a higher order extrapolation methodology is used − for the computation of ghost fluid value across the interface An excellent agreement between the present and published results are shown for Stefan flow problems induced by heat transfer (solidification and boiling).
