Hi,
I'm trying to simulate a hydraulic jump. Using VOF model, turbulent. Geometry is easy, slope of 5 degrees and a obstruction on the bottom. The water level before the opstruction is high, a little higher than the obstruction. Behind the obstruction, the water level is low and the velocity is much higher. But now hydraulic jump, the water level stays low. If I do experiments, I see a hydraulic jump. In my setup, Fr>1 andRe >10000. I use wall functions in a 2D geometry. Any idea wat I'm doing wrong? Is it possible to model hydraulic jumps in 2D or do I missed some physical understanding? Is there someone trying this before in OpenFoam? I have seen some fluent 2D calculations whit a hydraulic jump. Thank you! Arnout |
