摘要
逆流式涡流管,其切向孔进气压力、进气温度与分流系数变化时,测出涡流管中心孔流出的冷气体温度变化曲线,分析了冷气体的温度下降到摄氏零度以下的机理,得出了获得低温冷气体的条件。
The strongly swirling air flow caused in a counterblow vortex tube is examined experimentally. The influence of operating mode of the tube (inlet air pressure, temperature,…) on the effect of air flow total temperature separation are recorded and analyzed.
