Gas dynamic process formation in reflected shock tunnels and its validation purposes by hypersonic aerodynamic shock tube example

Abstract

Abstract The work for ensure the possibility of validation results for numerical simulation of gas-dynamic processes in a wide range with the use of modern techniques and certified measuring instruments are continued at the hypersonic aerodynamic shock tube facility. The method of precise experimental determination of the dynamic pressure at the critical section of the nozzle was tested. The results of calculations of the pressure field behind the section of the regular and elongated nozzles are validated. Measurements of the stagnation pressure before the nozzle were obtained experimentally.
