Hi, I'm doing simulation of a compresible flow in a pipe with some bumps on the wall.
I set the boundary condition of inlet pressure to be 10MPa and outlet pressure 7.4MPa, but it's so wierd that after long time iteration and the result comes converged( residual lower than 10e-4), the xy plot of static pressure shows the inlet pressure is different from the boundary condition I set (about 9.2MPa). Can anyone ever experienced that? Please help me. Thank you so much. and by the way, anyone knows how to set the friction factor in a pipe? Thanks again! |
