“…6, the free jet flow has a uniform momentum before impinging on the surface. The asymmetric momentum transport process associated with a skewed velocity field was responsible for the displacement of the maxima or minima of related quantities [3]. The effect of inclination angle became minimal with large L/D.…”

“…There is also interest in application on fan-powered vertical take-off and landing vehicles where the flow field can be simulated by an obliquely impinging circular air jet flow [2]. Besides the nature of complexity of the turbulent impinging jet flow, a jet issuing out of a pipe or nozzle and then impinging on a target surface with a change of flow direction upon impingement makes it difficult to rely on an analytical solution to predict the heat transfer process between the jet and target plate [2,3].…”

An experimental study investigated the effects of the inclination of an impinging circular jet on heat transfer from a horizontal flat plate. Local Nusselt number distribution was determine depending on inclination angle, jet-to-plate distance, and Reynolds number. The results show that the maximum heat transfer point moves toward the uphill side of the plate and that the maximum heat transfer decreases as the inclination angle decreases. The correlations were conducted to predict maximum and local Nusselt number as a function of Re, u, L/D, and x/D for three specific regions.
