Greetings!
I am trying to simulate flow field of cylinder submerged near a free surface. I am not able to validate the results with the published literature even qualitatively under the same nondimensional parameters. I believe the problem might be in the boundary conditions. I am attaching the boundary condition files for alpha, pressure and velocity. I need your kind feedback. Thanks for your time. Code:
//alpha dimensions [0 0 0 0 0 0 0]; internalField uniform 0; boundaryField { inletAir { type fixedValue; value uniform 0; } inletWater { type fixedValue; value uniform 1; } outlet { type zeroGradient; } ground { type zeroGradient; } cylinder { type zeroGradient; } sides { type empty; } top { type zeroGradient; } } Code:
//pressure dimensions [1 -1 -2 0 0 0 0]; internalField uniform 0; boundaryField { inletAir { type zeroGradient; value uniform 0; } inletWater { type zeroGradient; value uniform 0; } outlet { type zeroGradient; //p0 uniform 0; } ground { type fixedFluxPressure; value uniform 0; } top { type fixedFluxPressure; value uniform 0; } cylinder { type zeroGradient; } sides { type empty; } } Code:
//Velocity dimensions [0 1 -1 0 0 0 0]; internalField uniform (0.018 0 0); boundaryField { inletAir { type fixedValue; value uniform (0.018 0 0); } inletWater { type fixedValue; value uniform (0.018 0 0); } outlet { type zeroGradient; value uniform (0 0 0); } sides { type empty; } cylinder { type fixedValue; value uniform (0 0 0); } top { type slip; } ground { type slip; } } |
