TURBULENT FILM BOILING ON A HORIZONTAL CYLINDER--EFFECT OF TEMPERATURE DEPENDENT PROPERTIES

摘要

The turbulent film boiling from a horizontal cylinder is theoretically investigated considering the properties of the vapor as temperature dependent. In addition the effect of the thermal radiation from the surface of the cylinder on the film boiling heat transfer coefficients is studied. Some of the two-phase boundary layer characteristics are established. Comparison of the results from the present theory with relevant experimental data revealed very satisfactory agreement. An equation is proposed from the computational results with the aid of regression.
