Web1 de jan. de 2010 · Abstract. This paper provides a review of the stability characteristics of high speed jets. These characteristics not only play a role in the transition of jet flows to turbulence, in the traditional sense of hydrodynamic stability theory, but also are key to understanding the behavior of large scale turbulent structures in the jet.

Web25 de mar. de 2024 · The breakup of coaxial liquid jets in a co-flowing gas stream under the radial thermal field is studied by the linear instability theory. A simplified physical model … WebSummary. Theoretical results concerning the instability of axisymmetric jets are reviewed. For inviscid parallel jet flow the various parameters affecting jet instability as shear layer thickness, Mach number, temperature ratio, and external flow velocity are discussed. Furthermore, viscous and nonlinear effects are considered.
Web16 de dez. de 2010 · Instability of an evaporating jet is considered by Saroka et al. , who showed that the evaporation increases the growth rate of instability. Mashayek and Ashgriz [ 98 ] considered effects of the heat transfer from the liquid to the surrounding ambient, the liquid thermal conductivity, and the temperature-dependent surface tension coefficient on … Web2 de ago. de 2024 · The instability focuses near the interface where the jet-like motion approaches a new cell, decelerates, and diverges—hence the deceleration and shear-layer effects work together. In oil–water flows, the instability develops in the lower fluid, either in its depth or near the interface depending on the water volume fraction.
Web1 de jun. de 1994 · Abstract. A novel dispersion equation describing the instability of low velocity, liquid jets is derived using an integro-differential approach. The explicit form of the derived equation enables much easier prediction of the most unstable wavenumber and disturbance growth rate than does Tomotika's implicit, complex dispersion relationship.
