Summary

A physical model is presented to analyze the absorption phenomena on the basis of various interactions between the parameters and boundary conditions involved in actual situations. The boundary layer assumptions are used for the transport of momentum, energy, and species in an assumed laminar flowing film. The results show that 1) for larger flow rates, the heat transfer coefficient improves with the increase of tube diameter, whereas for smaller flow rates, the heat transfer coefficient is large; and 2) an optimum flow rate for a particular tube size can be estimated on the basis of flow rate and total mass flux relation.
