Convection, diffusion, and reaction in a packed bed reactor are governed by the following equations.

Convection, diffusion, and reaction in a
packed bed reactor are governed by the following equations in a cylindrical
domain with length 2 and radius 0.1:

Solve with the following parameters. You
should integrate to about 0.2:

Equation (11.48) governs the transient
reaction and diffusion with a Michaelis–Menten reaction in a porous media.
Integrate the equations to steady state using the parameters φ^{2}
= 10, v = 2, Bi_{m} = 20:
