Abstract EN
Many tall halls of big space volume were built and, to be built in many construction projects in the Far East, particularly Mainland China, Hong Kong, and Taiwan.
Smoke is identified to be the key hazard to handle.
Consequently, smoke exhaust systems are specified in the fire code in those areas.
An update on applying Computational Fluid Dynamics (CFD) in smoke exhaust design will be presented in this paper.
Key points to note in CFD simulations on smoke filling due to a fire in a big hall will be discussed.
Mathematical aspects concerning of discretization of partial differential equations and algorithms for solving the velocity-pressure linked equations are briefly outlined.
Results predicted by CFD with different free boundary conditions are compared with those on room fire tests.
Standards on grid size, relaxation factors, convergence criteria, and false diffusion should be set up for numerical experiments with CFD.
