摘要
通过防烟气扩散与控制烟风洞工作方式的分析对实验的立体模型进行设计 ;为了寻找阻烟最佳效果时的送风射流速度、厚度和射流角度 ,对防烟送风口进行了设计 ;并按不同工作方式观测烟气扩散与阻烟效果 。
Having analyzed different ways for prevention of smoke from diffusion and its control in air funnel,a model was designed for experimentation.A model of air supply inlet was designed to find out flow velocity,width and angle of the air inlet for the best prevention of smoke from diffusion effect.Experimental study was carried out according to different modes of operation,and the result of the experiment agrees with the theoretical analysis.
