HOW TO SIMULATE SURFACE DIFFUSION AND REACTIONS SIMULATION IN COMSOL MULTIPHYSICS. FIRST PART

This example deals with a phenomenon (convection-diffusion) occurring in a 2D domain
coupled to another phenomenon (diffusion-reaction) occurring only on a part of this
domain’s 1D boundary

Terrible, terrible video. Poor explanation, the guy was clearly not ready to do it and the audio is sufferable, to the very least. It feels that the guy was reading from a text on a piece of paper and that he have never used comsol before.

only one important questions that puzzled me in this expression -cs*TxDs where Tx come from and what does T refer to?

[@Simulation_World]

Here, csTx and csTy refer to the components of the gradient restricted to the plane tangential to the boundary where the interface is defined, that is, Boundary 5. Because this boundary is parallel to the y-axis, only
csTy is nonzero in this case.
T is temperature

[@annoon-i1l]

@@Simulation_World first thank you for reply. I think that the process is isothermal so the no need to take Ty or Tx, because they will =0, do you agree?

The video was really helpful for me. I went through both parts of the video but I didn't get a clear picture of what you have tried to simulate here. May I know the probem statement? I am in need of procedure to simulate Chloride diffusion in reinforced concrete. If you can explain what is that you have tried to simulate here, that would help me a lot to draw some relations between my problem statement and yours. Thanks in advance.😀

[@Simulation_World]

This example shows surface diffusion and surface reactions coupled to species transport to the reacting surface. In adsorption reactions it is necessary to model the surface concentrations of the active sites or surface complex as well as the bulk concentration in the gas phase. This device could be a catalyst, biochip, semiconductor component, or any process with surface-specific species.
