Abstract
A method and a system for diagnosing high-enthalpy shock tunnel flow field parameters are provided. In the method, the parameters of the reservoir at the end of shock tunnel and nozzle free flow are measured by using a contact measurement technology and a non-contact spectrum measurement technology to diagnose the high-enthalpy shock tunnel flow field. With the method, not only flow field temperature, pressure, component category and component concentration, but also non-equilibrium state information of the flow field and the effective wind tunnel working time can be obtained.
