- 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.
