Abstract

Flow boiling heat transfer (FBHT) can accommodate high heat transfer rates due to latent heat transportation. Its possible use is therefore potentially important to reduce the size and weight of space platforms and satellites. A comprehensive knowledge is also important for the safe operation of existing single-phase systems in case of accidental increase of the heat generation rate. For space applications, it is first necessary to identify the possible influence of microgravity conditions and, in the case of g influence, to evaluate the quantitative effect of reduced gravity on forced convective boiling heat transfer. The amount of existing research on flow boiling in reduced gravity is very small due to large heat loads required and reduced available room in a 0-g apparatus for experiments, as well as complexity of the experimental facility for microgravity environment. As can be expected, because of the reduced available data, coherence in existing data is missing. This paper will summarize the results of the research carried out on FBHT in microgravity, with special emphasis to the recent research carried out at ENEA, in the frame of an European Space Agency project.
