Experimental data are presented for natural convection heat transfer and for the point of inception of vapor formation for liquid hydrogen and liquid nitrogen. Nucleate boiling results with liquid hydrogen are also presented, indicating the so-called hysteresis effect with increasing and decreasing heat flux. The variables covered include heater surface material, roughness, and orientation.
