I am using LesInterFoam to sim
I am using LesInterFoam to simulate the film thickness on the wall of the conical section of a nozzle. I'm defining the velocity as an inlet boundary condition on the one side and fixed pressure as an outlet boundary condition on the other side. As a sub grid model I'm using the One Equation model.
The flow conditions for the gas phase are 4 bar and the Reynolds number is about 200.000. The liquid phase is fuel with a density of 750 kg/m^3 LesInterFoam calculation results in a static pressure discontinuity across the interface about a value of 800 Pa. I can't explain this discontinuity physically. Does somebody have some experiences with this kind of simulation? http://www.cfd-online.com/OpenFOAM_D...your_image.gif Relative pressures Thanks a lot for any suggestions, Andi |
