Car Air Filter
 

Dear Foamers,
I'm new in OpenFOAM. I want to model a Car Air Filter.
Do anyone know this case? How can I model it?

Thanks in advance for any reply!

Andrea

Hi Andrea,

I don't know your case, but I do know there is a solver for porous media in OpenFOAM. Perhaps that's usable to model the filter. Do you have a mesh etc?

Regards,

Gijs

Hi Gijs,

Thank you for your hint! I saw it, it's rhoPorousSimpleFoam and now I'm join with it.
I don't get mesh yet; I'm waiting for the CAD model.

Regards,

Andrea

Hi,
I have got mesh of air filter. I tried it with "rhoPorousSimpleFoam" and the run seems very well.
Now I want to run a transient case but there is not "rhoPorousTurbFoam".
Can I use "rhoTurbFoam" or I should use "turbFoam"? Now I'm trying the first but I think that porousZone doesn't run beacause I don't see "Creating porous zone: porosity" in the log file.
Another question: why when I make mapField I can't restart the run from the mapField condition? I obtain "floating point exception" and the run die.

thanks in advance for any aids

I asked before but no one responded. I don't know anything about air filters and I have really dumb question to prove it. Let me start out by saying that I am a girl and I know nothing about cars. For the past month my husband has been talking about how his car needs a new air filter and I'm going to surprise him by buying one and installing it in his truck! Step one was to start searching for where to buy them. I looked online and found this website that sells discount filters. I have no idea if these filters are the same kind of filters that go in vehicles. Can someone tell me if there is a difference between house air filters and car air filters? Does that place have the car kind? My second question is how to install them into the truck? Seriously, thank you so much for any help! Try to hurry with your answers, I want to have this done by this weekend!
