Heat transfer behaviour of supercritical nitrogen in the large specific heat region flowing in a vertical tube

This work investigates the heat transfer behaviour of supercritical nitrogen (SCN) for the ultimate goal of optimal design of cryogenic processes/systems. To this end, a comprehensive numerical study was carried out to evaluate the heat transfer coefficient for SCN flowing in a test section under representative conditions. This paper presents the results for nitrogen flowing vertically upward in a 2 mm diameter smooth tube. CFD simulations were...
