Heat transfer coefficients have been measured for superΒ° critical helium, circulated around a closed flow loop by a miniature centrifugal pump. Reynolds numbers in the 0"208cm i d by lOcm long stainless steel test section ranged from 1 x 10 4 to 3"8x 10 5 with pressures 3 to 20 atm (0"3 to 2 MN m -2
A literature survey of existing experimental findings on steady state and transient forced convection heat transfer to supercritical helium is given, and the deterioration of heat transfer, the influences of buoyancy force and correlations of heat transfer are also discussed.
