EXPERIMENTAL INVESTIGATION OF HEAT TRANSFER FOR A JET IMPINGING OBLIQUELY ON A FLAT SURFACE

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, theta, L/D, and x/D for three specific regions.
