Experimental data of pool film boiling heat transfer from horizontal cylinders in various liquids such as water, ethanol, isopropanol, Freon-113, Freon-11, liquid nitrogen, and liquid argon for wide ranges of system pressure, liquid subcooling, surface superheat and cylinder diameter are reported. These experimental data are compared with a rigorous numerical solution and an approximate analytical solution derived from a theoretical model based on laminar boundary layer theory for pool film boiling heat transfer from horizontal cylinders including the effects of liquid subcooling and radiation from the cylinder. A new correlation was developed by slightly modifying the approximate analytical solution to agree better with the experimental data. The values calculated from the correlation agree with the authors’ data within ± 10 percent, and also with other researchers’ data for various liquids including those with large radiation effects, though these other data were obtained mainly under saturated conditions at atmospheric pressure.

A study is reported of boiling heat transfer with saturated liquid nitrogen under atmospheric pressure at standard, fractional, and near-zero gravity. A drop-tower technique is used to achieve the reduced gravities. Because of the short test time available a transient technique using a sphere as a transient calorimeter is employed to obtain the heat-transfer data. This technique permits the ready acquisition of data in all boiling regimes from the film boiling region through nucleate boiling. Comparison is made with correlations for film boiling and for maximum and minimum heat flux and their corresponding Δtsat.
