Thanks for the answer! A, B and C are three separate fluid phases that don't mix with each other. A is a three-component mixture with one of the component in chemical reaction while B and C is pure substance. "However, you're also adding and removing mass from the domain against a reference of 298.15K so will need to add and remove heat from the phases. ", so the energy source term for phase A is -mass*(formation enthalpy of the component in reaction+sensible heat) or -mass*(sensible heat)? What is the energy source term for phase B and C?
