| Abstract | This paper presents a study on heat transfer enhancement by swirling impinging jets. The swirling jets were induced by inserting dual twisted tapes into jet nozzles. The effects of jet Reynolds number (4000 < Re < 16,000), jetto-plate spacing (2 < L/D < 8), tape twist ratio (y/W = 3, 4, 5, 6) and swirling direction were experimentally investigated. Numerical visualization was also carried out to study a behavior of the flow phenomena of swirling jets. |
