Hi,<\/p>\n

I am trying to simulate a flow where CO2 in two-phase (liquid+vapor mixture) is entering a pipe at a certain temperature and pressure. I also know the mass flow rate. The vapor quality of the mixture changes during the flow. Pressure will drop throughout the pipe, so the properties of the mixture will be changing as the pressure changes. How do I select the material in this case, because I couldn’t find liquid CO2 in the material database in Fluent. Also, what two-phase model, and phase interaction model would you recoomend in this case? I want to track temperature in this flow to study heat transfer in this case.<\/p>\n","protected":false},"template":"","class_list":["post-359644","topic","type-topic","status-closed","hentry","topic-tag-fluent-cfd-ansys-1","topic-tag-heat-transfer","topic-tag-two-phase-flow"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
