Parametric study of a simple tunnel fire model

I. Teleaga



First part of this paper presents an overview of some low Mach flow approximations to the compressible Navier-Stokes equations. Their derivation is based on rewriting the equation for the static pressure. With these derivations variable-density incompressible Navier-Stokes systems with non-zero divergence field are obtained. One of them is taken in order to simulate fires in tunnels. Using a modified projection method, a numerical parametric study with respect to the intensity of the heat source is presented.
