Received: 28 September 2017 Accepted: 19 July 2018 Inclined jet impingement is used for various industrial cooling applications. Its manufacturing and ease of applications is making it more popular day by day. The hot flat target surface is cooled using jet impingement. The jet is kept at an inclination of 15 –75° to hot target plate. The experiments are performed to study cooling effect with different configurations of inclined jets. Inclined jet with air as fluid having Reynolds number in the range of 2,000 ⩽ Re ⩽ 20,000 is examined for the circular cross section of jet. The target surface to jet perpendicular height (H) is taken as 0.5 ⩽ H/D ⩽ 6.8. The maximum cooled spots on the target surface are identified on the plate by analyzing maximum Nusselt numbers at different locations. The effect of H and (H/D) on maximum Nusselt number is presented. The investigation leads to equations for maximum Nusselt number for inclined circular non-confined air jet in terms of Reynolds number. Also analysis is carried out for ratio of average Nusselt number to maximum Nusselt number.
