摘要

Heat transfer characteristics of a circular turbulent impinging jet with a swirl were experimentally examined using air as a working fluid. A swirl was produced by inserting air from two exits on the side surface of a circular nozzle. The flow was visualized by a smoke-inducing method. Impingement surface temperature was measured using thermosensitive liquid crystal by transforming from color to temperature. Local heat transfer has two peaks due to the inserting angle. The swirl enhanced the impingement heat transfer, which was arranged by the ratio of circumferential momentum and axial momentum, within the present conditions.
