Heat transfer in forced flow helium at supercritical pressures Part 2, Correlation for Forced Convection Heat Transfer

摘要

The correlations for laminar and turbulent heat transfer in forced flow of He I under a supercritical pressure were given based on the experimental data for three test channels with different dimensions reported in Part 1 of this paper. Reynolds criterion, Rec, from laminar to turbulent was found to be around Re=1×10{sup}5, where the exponent of Re in the correlation changes from 1/3 to 0.58.
