interFoam/interIsoFoam - transient water jet - high velocities at interface

I tried to model a transient water jet inspired by the archerfish using ILES in OpenFOAM v1806 with MULES and isoAdvector.
I get very high velocities in some cells at the interface which are higher than the biggest inlet velocity (6 m/s). There are also oscillations behind the jet. I can get rid of those effects by using RANS. But a lot information about the jet shape gets lost. There are also oscillations in my DES case. It seems that these oscillations get affected by surface tension. How can I improve my LES results? Thanks! |
