Abstract
Application of computational fluid dynamics (CFD) for simulating fire-induced air flow in a large terminal hall will be discussed. The selected CFD model is based on Reynolds Averaging Navier-Stokes (RANS) equations method with k-e based turbulence model. The fire is taken as a volumetric heat source and buoyancy effects are included in equations for the vertical momentum and turbulent parameters. Air velocity, pressure and temperature distribution are the predicted.
The large terminal hall has a curved ceiling and so body-fitted coordinate (BFC) technique is required to divide the computational region into cells. Different fire scenarios are calculated.
