摘要：
In this research, experiments are carried out to investigate the heat transfer between the swirling impinging jets and an iso-heat-flux simulant chip (a heated epoxy resin plate) by inserting twisted strips into round tubes. In some range of flow Reynolds number, the effects of nozzle-to-plate spacement, the geometries of the nozzle and the thread intervals of the twisted strips are examined, then the radial distribution of Nusselt numbers on the target plate are obtained, so are the Nusselt number correlations. Meanwhile, the heat transfer characteristics of the swirling jet in both the stagnation region and the wall jet region are interpreted. In order to verify its heat transfer effect, the swirling jet is compared to the ordinary straight one.
