AB  - Theeffects of a turbulent inclined jet impinging on a horizontal flat surface wereinvestigated numerically with respect to the flow field and heat transfercharacteristics. Main purpose of the study was to show the effects of inclinedjet impingement on flow characteristics, which affects the heat transfer on asurface with a constant heat flux. Simulations were performed for differentdimensionless jet-to-plate distances (2 < H/D < 8), inclination angle ofthe jet (45° < α < 90°), and Reynolds number (1500 < Re < 30000).The heat transfer and fluid flow characteristics have been discussed usingtemperature contours and velocity vectors. Initial simulation results have beenvalidated with experimental data from the literature, and a fairly good agreementhas been achieved. Results showed that by decreasing the inclination angle, adecrease in the maximum heat transfer occurs. The ratio of the maximum Nusseltnumber to the stagnation Nusselt number increases as the jet angle isincreased.
