Determination of the interfacial area and mass transfer coefficients in the Taylor gas–liquid flow in a microchannel
The interfacial area in the Taylor (slug) gas–liquid flow in a microchannel was measured by the Danckwerts' (chemical) method, using CO 2 absorption from the CO 2/N 2 mixture into KHCO 3/K 2CO 3 buffer solutions, containing NaOCl as a catalyst. The rate of absorption was determined and the Danc...
