Two phase convergence problem
Hi. I'm simulating a two phase(gas and liquid) flow through some piping that consists of some bends and different pipe-sizes(mostly 12", 10", 8").
Flow: 6648m3/day liquid 100648sm3/day gas Op.pressure=8bar Density liquid=920kg/m3 Op.temp=80C Kinematic viscosity for liquid=15cSt (@80C)
I have troubles with getting a good convergence. The results I get shows that most of the streamlines ends up with 0 velocity midway throug the piping where I have a sharp turn, and narrow geometry. Is it a mesh-problem? It's my first attempt at a two phase simulation, so I could need som help..
