Physical characteristics of subsonic jets in a cross-stream

Abstract

This paper deals with local flow characteristics of subsonic turbulent jets in the presence of a cross-flow. For the various types of jet considered (a cylindrical jet and coaxial jets) the experimental results concern the axes and the velocity profiles in the plane of symmetry of the flow. In the case of the cylindrical jet, the shape of the universal axial velocity profile is defined, as are the law of velocity decay along the axis and the laws of variation of the thicknesses of the jet. Finally, the existence of a link between the axis equation and the law of axial velocity decay in the zone of similarity of the velocity profiles is established.

Breakup of a Round Liquid Jet in a Low Weber Number Cross Flow

“…This study was important in showing the connection between the shedding vortices from a solid cylinder, and shed vortices in a single phase JICF, which is generally only present in a range of Reynolds numbers, 250 < Re < 2x10 5 . Chassaing et al (1974) continued the work of Baines and Keffer (1962) by focusing on the trajectory of the jet, and defining planes of symmetry within the body of the jet. Using experimental measurements with pitot probes and hot wire anemometers, Chassing et al (1974) were able to develop a new method for evaluating the axis of the jet.…”

“…In the research of Camussi [7] and Chassaing [16], the time-averaged particle trajectories of the JICF can be approximately expressed as:…”

Physics-based scaling laws for confined and unconfined transverse jets

“…It thus represents one of the fundamental characteristics of the transverse jet and is often the target for scaling law development. A number of studies have been conducted to measure and scale the transverse jet trajectory (Cambonie et al 2013;Cárdenas et al 2012;Chassaing et al 1974;Chochua et al 2000;Fearn and Weston 1974;Gutmark et al 2008;Hasselbrink and Mungal 2001a, b;Kamotani and Greber 1974;Keffer and Baines 1963;Muppidi and Mahesh 2005;New et al 2006;Pratte and Baines 1967;Smith and Mungal 1998;Su and Mungal 2004;Yuan and Street 1998). Many of these studies sought to develop a universal trajectory curve with a single or reduced set of independent variables.…”
