Amplitude mismatch

I am performing CFD analysis of sloshing in a tuned liquid damper by applying base excitation in the form of acceleration. The results match well with experiments for a small excitation amplitude (A = 10 mm). However, when the amplitude is increased to A = 40 mm, the response pattern still agrees, but the amplitude does not validate against the experimental data. What could be the reason?
solver details: PISO, using multiphase volume of fraction, Pressure- PRESTO, k-w(SST), should we enable turbulence damping? I have tried reducing the time steps, not much impact in the results. |
