The application of holography to the study of shock wave formation in a shock tube
Abstract
A holographic method is used to produce a three-dimensional image of the unsteady flow of a propelling gas as it moves from a nitrogen-filled chamber into the air-filled channel of a shock tube having a 34 x 34 mm cross section. An analysis of the images shows that the compression waves which form the shock wave arise in the flow of a propelling gas directly behind the front of the unsteady shock wave.
