The experimental investigation is carried out to study the distribution of wall static pressure (Cp & Cpo) on the convex smooth surface by air jet impingement. A great deal of attention was paid to analyze the effects of orifice geometry for various flow and geometric conditions, a comparison of the wall static pressure coefficient is done for different orifice. The experimental results show that the wall static pressure on a convex test section is higher for rectangular orifice compared to other orifice. The wall static pressure decreases circumferentially from its maximum value at the stagnation point (θ = 0°) and also for higher Z/dh. Higher value of Cp and Cpo are obtained for unconfined flow. The experiments were performed with the following parameters: the jet Reynolds number (Re) = 10000–50000, the orifice-to- convex surface distance (Z/dh) = 1–5, Circumferential angle (θ) = 0° to 30°, Curvature ratio (D/dh), Orifice = Circular, Square, Triangle, Rectangle.
