Abstract
This paper presents a new computational method based on a multiphase model to deal with thermal interactions between compressible fluids and solids. In the present method, conservative governing equations for multiphase fields are solved with the numerical method for compressible fluids. The present method was applied to the natural convection in a enclosure cavity with a square cylinder conducting body. As a result of the computation, heat transfer in the multiphase field was reasonably simulated. In addition, through the numerical experiment for the helium leakage from a container, the applicability of the present method was discussed.
