Experimental Research of Heat Transfer from an In-Line Tube Bundle to a Vertical Foam Flow
要約
Development of heat exchangers with low consumption of primary energy resources and the enhanced heat transfer rates is the aim of our investigation. There are some ways of heat exchangers development. Usage of advanced coolants with the most suitable characteristics is one of the best and promising ways. We estimated that usage of aqueous foam as a coolant results in a relatively large heat transfer rate due to a small mass flow rate of such coolant. The main task of this work was to experimentally investigate the intensity of heat transfer from an in-line tube bundle to vertical upward and downward (after a 180-deg turning) foam flows. The influence of the foam flow parameters, such as flow velocity, direction of flow, volumetric void fraction of foam, and liquid drainage from foam, on the in-line tube bundle heat transfer intensity was determined. The influence of the tube position in the bundle on heat transfer intensity was investigated as well. The results of our experimental investigation are presented and analyzed in this paper. The results of investigation could enable one to create a modern and economic heat exchanger with simple and safe operation using a two-phase foam flow. It must be a compact, light heat exchanger with a relatively large intensity of heat transfer.
