Clogged artery, Help!
 
Hi, Im a student from Spain.

Im doing a study with Ansys fluent to simulate the extraction of a thrombus on an artery. Im trying to suck out the thrombus assuming that the artery is completely blocked.

Im not an expert on this software so im having some problems and maybe i wont express myself very well, so excuse me for that.

Im simulating the artery as a tube, I have the properties of blood of density and viscosity. My boundary conditions are: Wall on the wall artery, pressure outlet on the outlet(this is the open wall) and on the inlet i have tried with wall condition and with velocity inlet=0. The inlet is the wall where the thrombus is positioned, so is the wall that is blocked.

I didnt get good results, so any help will be great.

Thank you and excuse me for my english.

So you want to simulation displacement of thrombus with flow of blood. Am I right?

would you mind posting some picture with a description

I just want to study the pressure distribution on the thrombus, to see if i can extract it, but I think its necessary that walls can be deformed and I dont know if thats possible in Fluent.

Ive been trying to simulate this problem with FSI but it was too difficult for me because I didnt get any result.

Thank you very much
