Foam has an especially large inter-phase contact surface which allows using it as a coolant. Characteristics of one type of foam -statically stable foamdemonstrated its perfect availability for this purpose. Our previous investigations of heat transfer processes in statically stable foam flow showed that large heat transfer intensity may be reached at a small mass flow rate of the foam. Statically stable foam flow is the two-phase system that has number of peculiarities: drainage of liquid from foam, diffusive gas transfer and destruction of inter-bubble films. Those phenomena are closely linked with each other and make extremely complicated an application of analytic methods for the study of heat transfer in foam. Thus experimental method of investigation was selected in our work. Experimental investigation of the heat transfer process from the in-line tube bundle to the vertical statically stable foam flow was performed. Dependency of heat transfer intensity on flow parameters and on tube position in the bundle was determined. The results of the experimental investigation are presented in this paper.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
