The Structure of a Subsonic Compressible Rectangular Jet.

Abstract

A subsonic jet of air emanating from a rectangular nozzle of aspect ratio 16.7 has been investigated using hot-wire anemometry. The purpose of this investigation is to extend our knowledge of a rectangular jet from incompressible to compressible flow. Results of the hot-wire measurements show that a compressible subsonic rectangular jet behaves similar to an incompressible jet. It exhibits three distinct regions characterized by the decay of the mean axial velocity along the axis of the jet. These three regions are a potential core region, a two-dimensional type region, and an axisymmetric type region. The effect of increasing the Mach number of the rectangular jet was found to be the extension of the two-dimensional jet at higher Mach numbers.
