空気―水熱交換器内に多孔性材料を挿入する場合の伝熱流動特性

抄録

There are several methods for heat transfer enhancement. For example, one can attach various fins on the heat transfer surface, process the surface roughly, insert twisted tape, and so on. These methods increase the heat transfer coefficient or area by manufacturing changes to the heat transfer surface. However it is necessary to consider the problem on account of processing heat transfer area. In this study, heat transfer and flow characteristics performance of air-water heat exchanger by under the condition inserting metallic wire was evaluated, and compared the case of the fin. Pressure drop as compared with the case of the fins is significantly reduced.
