Abstract:

A Nusselt-type analysis was performed for laminar film condensation on the inside of a truncated rotating cone, which included the interfacial shear between the vapor and condensate, the vapor pressure drop, the thermal resistance in the condenser wall, and the condenser exterior cooling mechanism. An approximation of this analysis made it possible to find a numerical solution for small half cone angles greater than zero. A parametric study was performed of this approximate solution for various fluids, RPMs, half cone angles, and exterior heat transfer coefficients. A non-capillary rotating heat pipe containing distilled water as the working fluid was tested. It was rotated at 700, 1400, 2100, and 2800 RPM, and heat transfer rates of the heat pipe were determined experimentally for different vapor saturation temperatures corresponding to electrical power inputs ranging from 1 Kw to 7 Kw.
