Turbulent heat transfer characteristics of supercritical n-decane in a vertical tube under various operating pressures
To explore the effect of the operating pressure on the flow and thermal characteristics in a vertical tube with supercritical n-decane, the inner wall temperature along the streamwise direction, the applicability of empirical correlations and buoyancy criteria are studied firstly. The mechanisms in views of density distribution, velocity field, turbulence intensity, the thickness of the thermal bo
