The pulsating jet impingement has been subjected to research to provide enhanced heat transfer. Still, there is quite a mismatch between the results provided by various studies display mixed heat transfer behavior. The reason behind the complex heat transfer behavior is still unclear. The current study uses acoustically driven pulsation chamber, which adds pulsations to the steady flow. A wide range of Strouhal number (St = 0–0.7) for different surface-to-nozzle spacings (z/d = 0.25–8) are studied for a constant Reynolds number (Re) of 3265 and pulsation amplitude (A) of 40%. The experimental setup is validated with existing steady jet impingement data with acceptable accuracy. The results of the experiments show that there is minor effect of the change in St for a particular value of z/d. The maximum change compared to the steady jet lies within ± 5%. At small z/d, the high kinetic energy of the jet dominates the flow behavior, and there is a peak formation away from the stagnation point. With increase in the z/d, the average heat transfer reduces. Results shows a trend that pulsating jet with a higher St at low z/d and lower St at high z/d provide better heat transfer performance, although the change is minimal.
