Numerical simulations of heat transfer and fluid flow problems using an immersed-boundary finite-volume method on non-staggered grids

Abstract In this presentation we will describe the use of the immersed boundary technique for simulating fluid flow and heat transfer problems over or inside complex geometries. The methodology is based on a fractional step method to integrate in time. The governing equations are discretized and solved on a regular mesh with a finite volume non-staggered grid technique. Implementations of Dirichlet and Neumann type of boundary conditions are also presented and validated. Several phenomenologically different fluid flow and heat transfer problems are simulated using the technique proposed in this study. The accuracy of the method is second-order, and the efficiency is verified by favorable comparison with previous results from numerical simulations and laboratory experiments.
