Abstract

The effect of axial diffusion, usually neglected in mass transfer calculations, in investigated for the absorption process into a liquid film. The absorption takes place within a finite length of the film and the surface resistance is assumed to be constant. For such a system, several upstream and down-stream boundary conditions are analysed and the results are presented in terms of the overall Sherwood number. It is found that the effect of axial diffusion is appreciable for very short absorbing lengths or relatively low flow velocities. For long absorbing lengths, all cases considered are insensitive to the upstream and downstream boundary conditions.
