particle tracing

CYMa · November 13, 2009, 04:22

i am new in applying OpenFOAM.
May somebody tell me which FOAM i should use to simulate particle tracing in a gas flow (no chemical reaction between particles and gas).

Thank you very much!!!

Hi

Reading Nikas Nordin's thesis is a good start [1]. Then you should try out icoLagrangianFoam [2] If you want to learn the details about how lpt works in OpenFOAM read. [3] There are already some interesting posts on this forum, search for lagrangian or particle tracking.

I would discourage the usage of icoLagrangianFoam. It is sooo pre-1.5 (in 1.5 the particle system changed a lot and there are lagrangian-solvers that come with the distribution (some of them in the tutorials). ILF compiles on 1.5, but is not state of the art)

What pieces of code would you recommend instead? dieselFoam?

The last time I looked at it, it was "old school". Have a look at the solvers in $FOAM_SOLVERS/lagrangian (and there are additional solvers in $FOAM_TUTORIALS/lagrangian). If you're lucky you'll find an intermediate-class that fits your need and which you just have to plug into your solver
