TRANSPORT IN A HOLLOW CYLINDRICAL MEMBRANE

A detailed treatment has been given of radial transport in and through a hollow cylindrical membrane for two initial distributions of diffus ant within the membrane of practical interest. Expressions are given f or concentration distributions of diffusant and for unit length of mem brane, amounts present, fluxes through radial planes, and amounts tran sported up to time t across those planes. Some consideration has been given to forward and reverse flow and to relations between flow quanti ties characteristic of those transports. (C) 1997 John Wiley & Sons, I nc.
