摘要

对于空间狭小的地下停车场来说，消防安全是一个关键问题。在实验结果的基础上，采用数值模拟的方法研究了地下停车场喷气风扇辅助排烟的效果。讨论了射流风机布置和出口速度对烟温和能见度的影响。结果表明，利用射流风机辅助排烟能有效控制地下停车场烟气扩散。布置20个出口速度为8m/s的风机，可以加快排烟速度。

Numerical Simulation Analysis on Air Supply and Smoke Exhaust Assisted by Jet Fan in Underground Car Park

Fire safety is a key issue for an underground car park with flat and restricted space. Based on the experimental results, effect of smoke exhaust assisted by jet fans has been investigated in the underground car park by numerical simulation. The influence of jet fan layout and outlet velocity on smoke temperature and visibility is discussed. Results show that the use of jet fans to assist smoke exhaust can effectively control smoke diffusion in an underground car park. The arrangement of twenty fans with outlet velocity of 8m/s can accelerate the extraction of smoke.
