摘　　要：为改善空气射流(幕)的隔烟效果,根据涡旋运动的拟序性,研究增强涡旋运动的拟序性对空气射流(幕)隔烟的影响。通过2股相向错位空气喷射流加强涡流拟序性,采用理论分析及基于大涡模拟(FDS)的方法,展示射流涡流的拟序性现象,说明拟序涡流限制无序运动的原理、作用过程,证明增强涡旋拟序性能提高空气射流(幕)的隔烟能力,同时用实物试验验证了该方法隔烟的有效性。For the sake of improving the effectiveness of isolating smoke by air jet flow,the effect of the eddy quasi-ordering on the effectiveness was studied.The eddy quasi-ordering was enhanced with two opposite dislocation air jet streams.The phenomena of the eddy quasi-ordering shown by theoretical analysis and simulation using Fire Dynamics Simulator.The principle and process of out-of-order movement confining by quasi-ordering eddy were discussed.It was demonstrated theoretically and experimentally that the ability of an air jet flow to isolate smoke can be increased by enhancing the eddy quasi-ordering.
