Hi foamers,

I'm running a 2D flat wall film cooling case usig pisoFoam solver and SGS model with vanDriest damping function. I have set a very small time step, so the Co is lower than 0.5 during simulating. However the results are not as good as I have expected. I found that the velocity within vicosity layer is lower than the experimential data. I don't what waht error have I made. Can anyone help me?

ce 1.05;
ck 0.0472;
printCoeffs     on;
