debuger Guest Posts: n/a	Hi ! I'v been compute a 2D channel use periodic boundary and got a covergence ,also I found the value of pressure grident changed in "periodic conditions" form. My question is: whether or not I can treat the pressure gradient as the pressure drop?for example if the pressure gradient is 23Pa/m , as for 0.5m channels then the pressure drop is 0.5*23=11.5Pa? is that correctly? My second question is:there are two channels which have same profile,one is 2D model the other is 3D model and generally how difference the results of the two situations?
