Simultaneous Boiling and Forced Convection Heat Transfer From a Horizontal Cylinder to Water

This paper presents the results of experiments involving simultaneous boiling and forced convection heat transfer from horizontal cylinders to water in crossflow. In these experiments all of the following primary variables were varied: heat flux, crossflow velocity, pressure, subcooling, and surface material. Based on these data an empirical correlation equation is developed which permits one to predict the performance of a cylindrical heater in the presence of crossflow and boiling, provided only that its performance in the absence of crossflow (pool boiling) is known. This correlation equation eliminates the need to perform experiments in the presence of crossflow to ascertain the performance of a “crossflow-plus-boiling” cylindrical heater.
