Effect of fin on heat transfer around a tube in an aligned-arranged tube bundle was investigated experimentally, and the obtained results were compared with other arrangements, i.e. single tube, single tube row and staggered arrangement. It was clarified from the experiment, that the effect of fin begins to appear with larger fin spacing than the staggered arrangement, and the degradation in local heat transfer coefficient due to fin can be recognized not only in the downstream side of the tube, as observed in other arrangements, but also in the upstream side. As a result of this phenomenon, the degradation in average heat transfer coefficient becomes larger than the other three arrangements with the same fin spacing.
