✦ Synopsis

The proposed "'mesh step" model rcprcscnts the mass transfer process as a laminar concentration boundary layer whose development is periodically interrupted. The boundary layer develops along a given characteristic Iength at the end of which it undergoes partial mixing, i.e., it regresses to an earlier. less deve?oped stage. from which the devetopment starts again, etc. Thus the mixing effect of the spacer is represented by twu parameters:

The mesh size and mixing efficiency. This is compared with a "'constant boundary layer" model which assumes a faminar diffusion layer of constant thickness with perfectly mixed bulk Bow.
