Hello! I want to simulate the two-phase, two-component flashing flow of oil (very low vapour pressure) and a non-condensable gas. One of the phases is composed of pure gas and the other is a liquid mixture of oil and dissolved gas. The mixture flows inside a tube and the pressure drops along the tube due to friction. The mixture enters the tube saturated with gas, as pressure drops along the tube the mixture becomes supersaturated, at which point gas is released from the mixture and forms the second phase (pure gas). I was wondering if anyone ever simulated a case similar to this (either in Fluent or CFX) and could give me any tips on how to model the outgassing (in Fluent or CFX, which one is better for this case?). Any information or references are very welcomed!
