Pressure build-up with VOF in a closed domain -- CFD Online Discussion Forums

October 16, 2008, 04:26	Pressure build-up with VOF in a closed domain	#1
Juan Guest Posts: n/a	Dear all, I have problems trying to reproduce in FLUENT a pressure build-up phenomena due to external heat flux applied on the walls of a closed domain with two phases (liquid and gas)inside. The procedure recommented in FLUENT is the Floating Operating Pressure option. This works for a no-multiphase model and the solution is quite closed to the thermodinamic theory. But it doesn't for the multiphase: the pressurization rate is 50% more than expected. Did anybody face before this kind of problem? Thanks a lot. Best regards, Juan
