Revisit the COMSOL Example 14–3 for laminar flow with dispersion.

(a) Plot the radial concentration profiles for z/L = 0.5 and 1.0 for a second-order reaction with CA0 = 0.5 mol/dm3 and kCA0 = 0.7 minusing both the closed-vessel and the laminar flow open-vessel boundary conditions at the inlet. Is the average outlet conversion for the open-vessel boundary condition lower than that which uses the closed-vessel boundary condition? In what situation, if any, will the two boundary conditions result in significantly different outlet concentrations? Vary Pe and Da and describe what you find, i.e., CA0 = 0.5 mol/dm3.

(b) Repeat (a) for both a third order with
