Numerical simulation on temperature in wood crib fires

Temperature from burning wood cribs will be simulated in this paper by subgrid scale model fire dynamics simulator. A baseline gas phase uncertainty is determined for simulating crib spread scenarios. This based on a sensitivity analysis of key input parameters and their subsequent effect output variables that are important spread. Effects different grid systems, computing domains moisture contents the predictions were studied first then used to study gaseous sensitivity. The considered are: Smagorinsky constant, Prandtl number, Schmidt number. results show temperature have good agreement with experiment values 0.25, 0.7, 0.4, 5 turbulent respectively.
