Abstract
Mach number of shock wave propagating in a pipe is usually estimated by techniques using an average velocity of shock, a pressure history, etc. Mach number obtained from the pressure histories of the shock propagating between two stations is the averaged one between the stations. To obtain a local shock Mach number at a certain station, the pressure jump across the shock from a single pressure history is often used. In this case the pressure history is filtered, which makes it difficult to evaluate the local Mach number correctly. In this paper a dynamic characteristic of the pressure transducer is examined and a step response of pressure is utilized to obtain the local Mach number.
