Dear evereybody I am simulating a transient flow through a simple pipe. Inlet pressure changes with time.
For primary steady-state solution, the boundary conditions are: 1. pressure inlet equal to 5000 pascal 2. pressure outlet equal to 1000 pascal 3. rigid wall The results are so meaningless, for example average velocity is between 50 to 100 m/sec. Could you please help me? Should I change the boundary conditions? |

hi,
is it compressible or incompressible? please make sure that the 5000 pa corresponds to static + dynamic pressure...if it is incompressible.. and total or stagnation gauge pressure if it is compressible... or...decrease the residuals from default to 1e-5 or some thing ...and allow it till it any flow parameter such as velocity stabilizes... Regards, Jay |
