Abstract:
Gravity currents generated by smoke movement in
corridors are studied by numerically integrating the two
dimensional Navier Stokes equations. High resolution
solutions to these equations in the Boussinesq limit are
compared with salt water experiments to demonstrate the
validity of the model. Then the effects of heat
transfer are included and its consequences for smoke and
hot gas transport in corridors is assessed. Sample
numerical results are presented to illustrate these
phenomena.
