Mass Transfer of Mixed Gas Flow Crossing A High Temperature Graphite Cylinder with Chemical Reactions and In-Pore Diffusion

Abstract An experimental study on mass transfer with chemical reactions and in-pore diffusion was performed in cross flow containing oxygen past a porous graphite cylinder placed in a high temperature environment. Reynolds numbers ranged from 533 to 2490, and cylinder temperatures ranged from 848 to 1120°C. It is concluded that chemical reactions do not significantly influence the mass transfer, and that the effect of in-pore diffusion on mass transfer can be estimated by using empirical relations for the corrosion rate and mass transfer.
