This is related to Larsen-Borgnakke model. I have simulated the Bird's horizontal flat plate and my results only agree when i changed VariableHardSphere to LarsenBorgnakkeVariableHardSphere, choosing 5.0 for the relaxation collision number:
// Binary Collision Model // ~~~~~~~~~~~~~~~~~~~~~~ BinaryCollisionModel LarsenBorgnakkeVariableHardSphere; LarsenBorgnakkeVariableHardSphereCoeffs { Tref 273; relaxationCollisionNumber 5.0; } |
