Development of a method for determining flow parameters in impulse wind tunnels

Thermophysics and Aeromechanics Aims and scope

Abstract

Known approaches to the determination of flow parameters in the test section of hot-shot wind tunnels are analyzed, and ways towards their improvement are outlined. An algorithm for calculating flow parameters in short-duration supersonic high-enthalpy hot-shot wind tunnels using the experimental values of pressure in the prechamber, the total pressure behind the normal shock wave, and the flow velocity and stagnation temperature as a function of time, is developed. It is shown that the results of measurements and calculations using the developed algorithm for determining flow parameters fairly well comply with the calculation of flow parameters based on the gas-dynamic relations taking into account the losses of heat in the gas-dynamic path of the wind tunnel.
