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.
