The analysis of a jet structure inside a reverse chamber

Abstract

The paper presents experimental results for an axisymmetrical jet flow impinging with outflow through a reverse chamber. The test results include the average distributions and fluctuations of pressures on the impinged wall and the side wall of the chamber. The presented results cover further the mean velocities and the velocity fluctuations in the reverse chamber in relation to two velocity components: axial and radial. The purpose of the paper is to indicate the differences between different flow situations: the axisymmetrical free jet, the impinging jet hitting a flat surface, and a flow geometrically alike, however, restricted in outflow through a reverse annular chamber.
