STG-22 Review of Supercritical Fluid Heat Transfer

C. M. Laird

Supercritical fluid heat transfer occurs at temperatures and pressures that exceed the liquid-vapor critical point. This report reviews recent studies of the phenomenon, discussing both experimental studies and correlation developments. In comparison with recommended correlations, current HTRI calculations may be inaccurate for near-critical conditions. The range of inaccuracy depends on process conditions and may be strongly affected by fluid property variations. However, HTRI predictions should be reasonable for cases that are not governed by heat transfer near the critical point.
