竪型エジェクターによる増湿操作におけるガス側物質移動特性 Characteristics of Gas-Side Mass Transfer for Humidification in a Vertical Ejector with Liquid Jet
The characteristics of mass transfer accompanied by heat trasfer for humidification of air were experimentally investigated by using a vertical ejector with a water jet. The values of volumetric coefficient of mass transfer in the gas phase, kG a increased with increases in the mass velocity of air, G<SUB>i</SUB> and liquid, L<SUB>i</SUB>, and were proportional to G<SUB>i</SUB><SUP>1.29</SUP> and L<SUB>i</SUB><SUP>0.49</SUP> in a case of single nozzle. Moreover, the relationship between the values of volumetric coefficient of heat transfer in the gas phase, h<SUB>G</SUB>a and the operating conditions was investigated in the case of a single nozzle. As a result, an empirical correlation by which the observed values of h<SUB>G</SUB>a can be predicted within an error of ±15% was obtained.
