(a) Same as in Figure 18(b) but at s = 0.1 and showing the solution obtained from equation (B 18) in black dashed line. (b) Snapshot v φ = −2∂z Ψ 1 0 /(iω) in a meridional section of the theoretical azimuthal flow obtained from equation (B 18). We obtain an excellent agreement with the analogous snapshot from DNS (not shown).

The generation of mean flows is a long-standing issue in rotating fluids. Motivated by planetary objects, we consider here a rapidly rotating fluid-filled spheroid, which is subject to weak perturbations of either the boundary (e.g. tides) or the rotation vector (e.g. in direction by precession, or in magnitude by longitudinal librations). Using bo...

Hasegawa-Wakatani system, commonly used as a toy model of dissipative drift waves in fusion devices is revisited with considerations of phase and amplitude dynamics of its triadic interactions. It is observed that a single resonant triad can saturate via three way phase locking where the phase differences between dominant modes converge to constant...
