Abstract
The paper presents the results of a numerical study of flow gas dynamics and integral parameters of the flow at the channel entrance located behind a conical or plane shock wave. The free-stream Mach number range is М = 2 - 4 and the range of the slopes of the compression surfaces of the wedge and cone is δ= 10 - 90°. Data on the flow structure at the channel entrance, mean-mass Mach numbers, total pressure loss, and flow rate coefficients are obtained. A comparative analysis of these parameters is performed, and advantages and drawbacks of the channel entrance positions in various types of the flow are noted.
