湿帘中气-液传质系数及压降的测定

Determination of Air-water Mass Transfer Coefficient and Drop of Pressure in Wet Curtain

用气-水逆流接触法测定了湿帘中的传质系数和压降，得到关联式。试验结果表明，空气和水的质量流速对传质系数和压降均有影响，但前者的影响比后者大。

The mass transfer coefficient and drop of pressure in wet curtain are meassured bymeans of counterflowing. Two formulas are obtained. The experimental results show thatboth air and water mass rates have effects on the mass transfer coefficient and the drop ofpressure while the former was more effective than the latter.
