2D Boundary Surface-Reaction Coupling

This exercise is based on the lecture notebook L8_surface_reaction_2D_boundary_coupling.ipynb.

Task¶

Model a 2D convection-diffusion bulk phase coupled to a catalytic wall with Langmuir-type surface coverages.

Questions¶

1. Implement the bulk transport model and the surface balance using the array layout from the lecture notebook.

2. Verify that the weighted surface-site balance remains equal to one along the reactive wall.

3. Plot the final 2D bulk concentration fields and the wall coverage profiles.

4. Change the adsorption rate of species A by a factor of two and describe the effect on outlet A and B concentrations.

5. Check that all bulk concentrations and surface coverages remain non-negative.

Deliverables¶

Submit the final plots, scalar validation checks, and a short discussion of how a boundary source differs from a volumetric source term.
