摘要：

A rigorous mathematical model is developed to describe chemical absorption of carbon dioxide in a failing-film micro-contactor. Compared to previous models described in literature, hydrodynamics in both phases is accurately captured by the Navier-Stokes equations. By this means, backmixing effects can be accounted for. Furthermore, the interface position is directly determined using the level-set method. The developed model is validated with experimental data obtained from literature and good agreement is established. On the basis of the validated model, detailed sensitivity studies are performed to investigate the impact of process parameters.
