Volumetric mass transfer coefficient
My objective is to evaluate overall volumetric mass transfer coefficient, using CFD, for CO2 absorption from Air (gas) to Amine (liquid) with no reactions.
Using basic definition "N*a = K_L*a*(C_L_eq - C_L)". Where N is molar flux, K_L*a is volumetric coefficient and C_L_eq and C_L are concetration at interface (in equlibrium with gas phase conc) and bulk concentration. All values pertaining to CO2 in liquid ammonia/amine.
Can we evaluate K_L*a from hydrodynamics and concentration profiles in CFD?
My approach could be
