Velocity Loss Measurements on Shocks in a Shock Tube
Abstract
In the shock tube developed at Princeton as an instrument for the study of transient fluid dynamics, the determination of incident plane shock conditions is accomplished through a knowledge of the temperature and pressure of the undisturbed air and the incident velocity of the shock. The incident velocity is measured by timing the transit of the shock between two stations in the tube preceding the point under study. While a simple theory of flow in the tube indicates that the shock proceeds through the tube with a constant velocity for a time, it is to be expected that dissipative effects operate to cause a gradual decrease in the shock strength and velocity. The presently reported work was undertaken to measure the amount by which the shock velocity decreases in its travel through the tube.
