Assessment of performance of turbulence models in predicting supercritical pressure heat transfer in a vertical tube

We have assessed and categorized representative models developed over the last two decades according to their ability to represent/capture important physics that we have identified. We demonstrated that indirect buoyancy effect is insignificant and hence its modelling can be simplified (contradicting conventional assumptions). The work provides valuable guidance for modellers, and was highlighted as one of 12 key publications in the field in Annual Review Fluid Mechanics 2013,45:495-525 (page520). The topic of supercritical fluid heat transfer is important to many emerging technologies, including new-generation nuclear reactors and supercritical CO2 air-condition systems.
