Numerical simulation and evaluation of natural smoke exhaust for straight corridor in high-rise buildings

Simulate the process of natural smoke exhaust for straight corridor in high-rise buildings with a field-zone compound model. Considers various components that affect the natural exhaust such as wind direction, wind speed, position of fire room, width of corridor, dimensions of exterior windows, season and length of corridor, etc. Obtains some conclusions through an analysis of the simulating results. The result shows that natural smoke exhaust should be used effectively in the corridor, the length of which is within 30 meter, to ensure people evacuate safely in fire building.
