摘要	High-speed flows over a cavity produce remarkably local heat augments. Heat transfer characteristics of compressible flow over a cylindrical cavity were revealed using wind tunnel experiments and computational analysis. Heating augmentation induced by cylindrical cavities is significant near the trailing edge of the cavity and distributed in a finite width along the spanwise direction. The heating augmentation of the cylindrical cavity decreases with the decrease in the ratio of cavity diameter (D) to cavity depth (H). Relationships between heat transfer and flow structures of the cylindrical cavity are observed. 3D geometric features of the cylindrical cavity lead to the formation of slant recirculating eddy and the existence of symmetric open flow regions in both spanwise sides of the closed cavity.& nbsp;(c) 2022 Elsevier Masson SAS.
