摘要
通过模型实验确定了形成稳定吹吸流场的条件及这一条件下吹吸流量比和喷口宽度的变化范围。回归分析得出了该气幕式排风罩有效控制距离的计算式。
By modelling experiment determines the conditions under which a steady push pull air velocity field can be built and maintained and the related ranges of the air volume ratio and width of the air supply opening. Obtains a regression formula for predicting the effective control distance of the hood.
