Helium was condensed on the wall of a vertical copper tube (14 mm in diameter, 32 mm long) in the experimental range: vapour temperature in the tube -4. 1-5.0 K; heat flux -0.5-86 mW cm-2; temperature differences across a liquid film -0.01-1.3 K; film Reynolds numbers -3-380. It was found that the h
## Abstract Because of the rapid properties variation of fluid under supercritical pressure, there is a violent secondary flow in a heated pipe, which will certainly complicate the heat transfer of fluid in a pipe under supercritical pressure. In this paper, a numerical study is conducted for the l
