Abstract: The efficient simulation of low Mach number flows still poses difficulties. While the flow is often incompressible, in a lot of applications, the Mach number or the compressibility properties vary strongly in time or space, for example in nozzle flow or laminar combustion. Here, we will focus on fires in road tunnels, where the strong heat sources make parts of the flow compressible. Standard compressible flow solvers have accuracy and convergence problems at low Mach numbers. On the other hand, standard incompressible flow solvers cannot deal with strong temperature or strong density gradients.
