Abstract

Preconditioning method developed by the authors was coupled with Building-Cube Method(BCM) which can simulate flows around a complex-shaped body. In this study, this method is applied to the simulation of thermal convective flows around an arbitrary-shaped body. First, forced and natural convections around a cylinder are calculated and the results are compared with the experiments and the previous numerical results to validate the calculated results. Second, natural convection around a fin-shaped body is calculated and the availability of this method to practical problems involving a thermal convective flow is discussed.
