Краткое описание

The local and integral characteristics of two series of afterbodies with different external contours tested in Russian and foreign wind tunnels are compared. The influence of the flow around the models (separated or non-separated), test section blockage ratio, free-stream Mach number M, and jet pressure on the afterbody characteristics and the range of scattering of the data obtained by different authors is demonstrated.

Ключевые слова: afterbody, nozzle, drag, wind tunnel, turbulent flow, jet, experiment, CFD
