Hello everyone!I am a freshman in £ãÆ£Ä and I am doing multiphase flow with water and air.Now I have a confusing problem about the pressure.
In v monmentum equation,if we only consider invisid flow,the equation will be
if we consider u v are both equal to zero,then the equation becomes
for my case,I give initial guess as hydrostatic pressure -rou*g*y
So after derivative,it becomes -rou*g-d(rou)/dy*y
Therefore anyway there is something left!
I am using roe scheme and coupled solver.What I should do to give right correction or some other suggestions?
Thanks for any suggestions!
