What physics do I need to model clogging of a vein? (very similar to electrodeposition tutorial)

If I have a species entering a vein at some velocity, how would I model the reaction with the surface and thereby build up of particles on the wall?

I know I need some mass transfer equation (let's say dilute species module) and I need laminar incompressible Navier stokes module.

What other modules/physics would I use to model the reaction with the wall and subsequent build up of particles
and
would I just use "moving mesh" module similar to electrodeposition module?

A list of suggested physics or examples would be of great help. This set-up should be very similar to the electrodeposition example

Thank you
Alex

Hey Alexander,

did you find a solution to your problem? I am interested in clogging of porous media / fractures by paricles.

all the best,
florian

You should use the Moving Mesh capability as in the electrodeposition example. You’ll see other examples of its use in the Microfluidics Module for two-phase flow. Regarding the species transport part, it’s hard to predict whether or not you may need more advanced capabilities beyond what’s available in the basic COMSOL package. That probably depends on the criteria for particle/plaque build-up.
