Schematic image of a diverging free jet illustrating the change of its mean velocity profile and widening of the mixing layer. Curves 1 and 2 correspond, respectively, to the internal and external boundaries of the mixing layer.
Plots of U d(x, y), V d(x, y), and Ωd(x, y) versus y for b 0 = 0.1, q = 3, r 0 = 0.5, : (a) U d(0, y); (b) U d(8, y); (c) V d(0, y); (d) V d(8, y); (e) Ωd(0, y); and (f) Ωd(8, y).
The dependences (a, c) of the gain factor and (b, d) the wave phase velocity on the sewing-point y 0 for (a) and two values of x (x = 4 (1) and x = 8 (2)); and for (b) x = 8 and two values of (S = 1 (1) and S = 4 (2)).
The dependences of the phase velocities on sewing-point y 0 for x = 8: (a) crosses and circles; (b) crosses and circles; (c) crosses and circles; the dependence of the dynamical longitudinal flow velocity is shown in a, b, and c by heavy line.
The dependences of (a) the gain factor Γ0, (b) the wave phase velocity v ph0, (c) the wave number K 0 and (d) the wavelength λ on the distance from the nozzle x for .
