Abstract

In the fields of architecture, machinery, and electronics, engineering problems frequently includes heat transfer phenomena that the energy is transferred from a high-temperature solid to a fluid. In order to precisely simulate the problem of heat exchange, a thermal analysis between solid and fluid should be performed not separately but simultaneously. In this study, we developed the code to calculate temperature and flow. For the fluid-solid calculation, the work of separating the fluid and the solid domains, and the automatic creation of the interface between the fluid and the solid were performed. The result of the fluid calculation provides the boundary conditions for the solid temperature in each iteration. The analysis code was verified by comparing its results with the experiment on the natural convection. The three-dimensional problem with the cube as the heat source was analyzed by considering the fluid-solid interaction.
