Experimental data on average heat transfer from the surface of a single-cavity diffuser-type dimple streamlined by a pulsating air flow were obtained in the study. It was found out that when the dimple is installed at 0 and 60 deg to the flow, different mechanisms of large-scale vortex formation are implemented. As a consequence, reasons for heat transfer enhancement in the dimple are also different.
