Wake Vortices in Jets in Cross-Flow

ASME-JSME-KSME 2011 Joint Fluids Engineering Conference: Volume 1, Symposia – Parts A, B, C, and D, 2011
The objective of the current experimental study is to investigate unsteady wake vortices of jets in cross-flow in order to (1) explore the effect of various excitation techniques, their parametric dependence, and impact on the flow field, and (2) provide detailed flow visualizations for a range of velocity ratios.

Expansion of a turbulent gas jet in a wake

Fluid Dynamics, 1966
Results are presented of an experimental study of the expansion of an axisymmetric heated gas jet in a uniform external wake flow. The experimental results are compared with calculation using the method of the equivalent problem of heat conduction theory (a summary of the notation is given at the end of the paper).

Free Turbulent Flows: Jets and Wakes

2015
In this chapter, self-similar solutions of free subsonic jets and wakes are established. These solutions can be used to characterize some properties of the mean turbulent flow itself, to assess turbulence models, and also to provide an analytical solution for the mean flow field under some assumptions.

Spatial Instability of the Inviscid Jet and Wake

The Physics of Fluids, 1966
The stability of the plane inviscid jet and wake is investigated for possible growth in the downstream spatial direction. The combined stability problem in space and time is also explored and numerical results are presented for growth factors and phase velocities.

Investigation of the microstructure a turbulent jet in a wake

Fluid Dynamics, 1966
The study of the characteristics of the turbulence in the boundary layer and in free jets is one of the most important problems of the aerodynamics of viscous fluids. The accumulation of information on the pulsation characteristics of jet flows and the establishment of the corresponding governing laws may serve to verify the basic hypotheses of the ...

On two-dimensional laminar wakes and jets

Journal of Fluid Mechanics, 1969
The flow fields in two-dimensional, isoenergetic, viscous free mixing with constant β and with initial velocity profiles deviating slightly from those given by wakelike solutions of the Falkner-Skan equation for that β are considered. The similar solutions of the Falkner-Skan equation are investigated in more detail than in the past, e.g.

Effect of the wake on flow in an annular jet

Journal of Applied Mechanics and Technical Physics, 1974
The flow of an annular jet in a channel is studied. The effect of the Mach number of the wake on the structure of the jet is determined. It is shown that with a near-sonic velocity a reorganization occurs in the mode of flow from an open to a closed base region accompanied by a reduction in the level of pressure pulsations.
