Condensation heat transfer parameter measurements for a rotating space heat rejection system

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

A rotating, flat plate condensation experiment has been developed to investigate the heat transfer and fluid motion properties of the Bubble Membrane Radiator (BMR). The BMR is a proposed heat rejection system for space applications which uses working fluid condensation on the inside surface of a rotating sphere to reject heat to space. The flat plate condensation heat transfer experiment simulates the microgravity environment of space by orienting the axis of rotation parallel to the gravitational vector and normal to the surface of the plate. The condensing surface is cooled to simulate the rejection of heat to cold space. The results obtained include relationships between the overall heat transfer coefficient as a function of the temperature difference between the working fluid and the cold environment, both placed in dimensionless groups, and plate rotational speed. These investigations are used to provide the technology background needed to evaluate the feasibility of using the BMR in space and ground systems.
