Abstract
Results of a numerical and experimental study of flow-field characteristics in the test section of the Т-313 supersonic blow-down wind tunnel of ITAM SB RAS at Mach number М = 7 are reported. The distributions of local Mach numbers, stagnation temperatures, static pressures, angles of flow deflection from the test-section axis were analyzed. For comparison, distributions of Mach numbers across the flow at several stations at М = 5 and 6 are reported as well. We show that, in the T-313 wind tunnel, two-dimensional nozzle inserts can be used to perform experiments at М = 7.
