Popis:	By the flow visualization study, it was shown that the flow in a heat exchanger was quite different according to the tube arrangement, and the flow between the fin plates in the vicinity of the tube was three dimensional one including the vortex street. A comparison between the observed results and heat transfer data was discussed. By the naphthalene sublimation study, a particuler distribution of local mass transfer coefficient on the fin surface was discovered, which was due to the vortex street generated in a boundery layer. With a comparison between the heat transfer and mass transfer data, it was shown that the naphthalene sublimation technique was applicable to the heat exchanger.
