Beschreibung:
  • Applying a low-Mach asymptotic for the compressible Navier-Stokes equations, we derive a new fluid dynamics model, which should be capable to model large temperature differences in combination with the low-Mach number limit. The model is used to simulate fires in vehicle tunnels, where the standard Boussinesq-approximation for the incompressible Navier-Stokes seems to be inappropriate due to the high temperatures developing in the tunnel. The model is implemented using a modified finite-difference approach for the incompressible Navier-Stokes equations and tested in some realistic fire events. Copyright © 2004 John Wiley & Sons, Ltd.
