Wall-Jet Electrode and EC Processes

The convection-diliusion equations relevant to the EC mechanism in the wall-jet electrode geometry under steady-state conditions are as follows  

First we will substitute r] into the expressions for Vr,t] o and and express 

From the definitions of f and / we can substitute into Eq. (8.6), so long as we take care in determining the correct substitutions for the derivatives  

Substituting the expression for A and recognising that / appears on the right-hand side  

Note that overall we have multiplied by / A D) to remove dimensionality, after making the substitutions. So for Eq. (8.7)
