Hi everyone
I am a beginner in CFD field. I am doing CFD analysis of pipe having convergent and divergent portion (like venturi) in between. At inlet Pressure is 1.7 bar temp 372 k and mass flow 260 kg/h. I dont know any property at outlet. Which bc i should take at inlet and outlet so that i can see pressure drop due to venturi? please help ! |

if incompressible, use static pressure-inlet and pressure outlet (keep outlet pressure to 1 bar atmospheric - or if you know the exact value).
For compressible case, use mass flow at inlet and pressure static at outlet. This should be straightforward and easy to converge. Btw, are you doign single or multiphase (cavitation in venturi's etc?) Cheers, CFDtoy Quote:

Hi
Thanks for your reply. I am considering compressible fluid with single phase. But my outlet pressure is not atmospheric still i should consider static atm pressure at outlet? Thnaks |
