受限空间烟气运动的盐水模拟实验初探

Experimental Study of Salt Water Simulation of Smoke Movement in a confined Space

考虑到盐水在清水中扩散过程与烟气在受限空间内运动的相似性，本文用实验的方法，初步探讨了用盐水的扩散来模拟烟气在建筑物（单室）内运动的可行性。并对烟羽流主轴线速度和顶篷水平分层烟气流厚度的生长规律进行了测量。本文所得结果基本合理，正确，对建筑火灾烟气控制和人员疏散有参考作用．

Considered tle simularity between the diffusion of salt in water and the movement of smoke in a confcned spdce,the feascibility to simulate the movement of smoke in a building (separate room)by using saet water modeling was studied and the normal-axis-speed of smoke plume and the growth law of smoke layer was measured withexperimental method in this study.The experimental resultS are plausible and can beused for reference to control smoke movement of room fires and evacuate people from aburning room
