Few Challenges Associated with Developing 1-D HTC Correlations for Supercritical CO2

Abstract

Canada among many other countries is in pursuit of developing next generation (Gen-IV) nuclear-reactor concepts. SuperCritical Fluids (SCFs) are expected to play a major role in the Gen-IV Nuclear Power Plant (NPP) applications.

SC CO₂ is proposed to be used as a modeling fluid to study the thermodynamic behavior of SCFs (especially water) as CO₂ reaches supercritical conditions at relatively moderate temperature and pressures. A major objective in conducting SC CO₂ experiments is to develop 1-D heat-transfer correlations that can be used to predict temperature profiles and used in other rudimentary heat transfer calculations. This paper presents some of the challenges associated with 1-D heat-transfer correlations.
