Abstract
The results of an experimental study of the aerodynamic characteristics and heat transfer under a jet flow past a spherical-cavity obstacle are presented. It has been revealed that in a spherical cavity the flow becomes nonstationary and is characterized by low-frequency oscillations of local values of the heat flow density. The heat transfer intensity in a hollow is lower than on a flat obstacle, and in the region of depression this decrease is practically completely compensated by an increase in the heat-transfer surface area.
