I have a cad model of the human airway tree. I want to do steady-state velocity and pressure analysis as well as particle deposition simulation study using comsol.
Particle diameter- 1micron
particle density- 2000kg/m3
Number of particles to be injected -10000.
Particle inlet- Inlet of geometry
Outlet- escape
Wall- Trap
How can I do that?
Do I need to perform steady-state continuous flow first then unsteady particle tracking?
Please help
P. S- I need particle deposition to look something like this.
Dear Shahid Habib Khan
You have several choices;
1- Just simulate steady state fluid flow and add particles on post processing (yeah it is possible).
2- Simulate steady state fluid flow first and then active" Particle Tracing Multiphysics" and solve it for transient and use fluid flow from steady.
3- Simulate both fluid flow and " Particle Tracing Multiphysics" at the same time in transient simulation.
Thanks Amir Reza Ansari Dezfoli . I used the second one and got results.
Another question- How to calculate particle deposition efficiency(PDE) in a particular region? Like I have to make plots of PDE of particular regions in post-processing. How can I do that in comsol?
Shahid Habib Khan
You can do it in the same way I described in reply to your other question (https://www.researchgate.net/post/How_to_find_particle_deposition_efficiency_based_On_forces_using_comsol)
