Heat transfer in turbulent planar offset attaching jets with small initial offset distances

Measurements of the mean heat transfer coefficient from the wall below turbulent offset wall attaching planar jets were performed for jets with Reynolds numbers (Rej) of 21,800–54,500. The jets were initially offset 0.2–1 times the initial jet height (Hj) above the wall. The Reynolds number dependence of the maximum Nusselt number varied with offset distance from Rej0.64 for the flows with an offset distance of 0.2Hj to Rej0.77 for flows with …
