Steady state Inlet port flow analysis
Guys, I'm having a nightmare trying to correlate my predicted results with measured data. Basically, the predicted pressure drop across the valves are consistently about half the measured values, i.e.
predicted DP:3-4kPa Measured DP: 6-7kPa
Test case details:
STAR-CD v3.26, meshed using ICEM CFD
Steady State inlet port flow analysis at various lift values
Turb models used: k-e (standard and RNG)
Wall functions: Standard
Tetrahedral mesh with prisms (Y+ values checked, and they seem ok)
Discretization method: MARS
Right now I'm trying to use non-equilibrium wall functions, don't know how that will go.
Anyone with some ideas how I could improve this? Thanks so much in advance.
