Abstract

Abstract

Experiments were conducted in a natural circulation loop to investigate the effect of buoyancy and flow acceleration on the heat transfer of supercritical CO₂. A new heat transfer correlation is developed based on the experimental data. Results show that the buoyancy is the main influencing factor for the heat transfer deterioration in natural circulation condition. The new correlation could predict the heat transfer of supercritical CO₂ well.
