How to use dynamicKEqn turbulence model in DPMFoam?

zhangxc0223 · November 1, 2018, 02:04

Hi, all. I am trying to use DPMFoam to solve a LES two-phase flow, with using the dynamicKEqn turbulence model. But it gives the error message that

Code:

Unknown LESModel type dynamicKEqn

Valid LESModel types:

2
(
Smagorinsky
kEqn
)

So, I would like to know how to add this dynamicKEqn model into the solver?

Regards.
Matthew

Hi Matthew

Did you manage to solve the problem?

I am also facing exactly same problem as yours. When I use any other LES model (except Smagorinsky and kEqn) with DPMFoam Solver, solver reports that no such model exist. However all LES models are available for single phase solver (e.g. pimpleFoam). I wonder if we can use other LES models with DPMFoam?

Hi, you need to compile the new model in DPMTurbulenceModels.C.

Hi Matthew

As I am relatively new to this compilation and C++ programming, I am not sure about the exact procedure, how can I add the dynamicKEqn model in existing DPMFoam solver.

can you please elaborate a bit?

It would be a great help.
