✦ Synopsis

The dependence of the heat transfer on pressure is studied for a horizontal plane surface in liquid helium, liquid hydrogen, and liquid nitrogen in the range 0.03 < P/Pc < O. 9: a maximum of the maximum heat flux density ~im,mWaS found at ~ 0.35Pc. For helium, additionally, the dependence on the inclination of the surface against the horizontal was determined.

A general representation for the dependence of the reduced maximum heat flux density "qm/~Tm,m on the reduced pressure P/Pc is given which also describes adequately well the results obtained with other cryogenic liquids.
