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
