Interferometric Study of Supersonic Phenomena. Part 1. A Supersonic Air Jet at 60 lb/sq in Tank Pressure

Abstract

The report is the first of a series describing optical, especially interferometric studies, of supersonic phenomena. A discussion of a Zehnder-Mach interferometer is given, showing the way fringes are produced, and the effect of various fringe widths and orientations. A supersonic air jet from a 10-mm diameter streamlined orifice at 60 lb./ sq. in. tank pressure was analyzed. Pressures, temperatures, Mach numbers, and velocities were calculated from the density values in the jet and the initial conditions. Shock strengths, entropy changes, and conditions at the orifice and slip stream are found generally in good agreement with theory.
