Simulation on spread of fire smoke in the elevator shaft for a high-rise building

Theoretical and Applied Mechanics Letters, 2014
Spread of fire smoke in the elevator shaft of a high-rise building is influenced by many driving facts. We simulate smoke spreading in the elevator shaft, stair room, and pre-chamber with and without different supplied pressurized air.
