Abstract

Re-evaluation of high mass flux literature data from evaporation and absorption experiments suggest the validity of yBM as a good correlation variable for predicting gas phase mass transfer at high transfer rates. This was done by testing Greiner and Winter's engineering model where yBM explicitly emerges after manipulating their model equations. The manipulated model agrees well with the literature data within the range of 0.961 ≥yBM ≥ a 0.549 and 7.3333 ≥ B ≥ −0.4757 which covers the mostly commonly chemical engineering conditions and geometries. Thus, the yBM serves not only as a good correlation variable as has been commonly used under low to moderate mass transfer rales, but also applies to the controversial case of high mass transfer rates.
