The present research is an experimental study of pool boiling heat transfer from cylindrical heater surfaces immersed in saturated FC-87 and R-123. The baseline heater surfaces tested are plain, integral-fin with 709 fins/m, and commercial enhanced (High-Flux and Turbo-B). In addition, a highly effective micro-scale enhancement coating is applied to the plain and integral-fin surfaces to augment nucleate boiling heat transfer. Experiments are performed to understand the effects of surface micro-and macro- geometries on boiling heat transfer. The boiling performance of the micro-porous-enhanced plain and integral-fin surfaces are compared with the High-Flux and the Turbo-B surfaces. At high heat-flux conditions, the breakdown of the bulk liquid feed mechanism reduces boiling enhancement from the cylindrical surfaces.
