縮流形フィンが加熱体表面の熱伝達に及ぼす影響について

抄録

A contraction fin, which plays the role of an extended surface, the acceleration effect and the wall jet, is proposed in the present study. The local heat transfer was examined experimentally on a heated surface with and without fins. The effects of the fins depend on contraction angle and the ratio of fin occupation across the section. Thermal performance of this fin was compared with those of other fins. Flow visualization was also performed for corresponding to the local heat transfer, by the smoke wire method.
