0 Þ for χ ¼ 1 = 3 (red) and χ ¼ 3 (blue), with varying t Þ relative to the initial value p FIG. 7. Change of the Casimir momenta Δ p c; χ ð c; χ ð L ). The panels coarse-graining levels (indicated by line styles in the legend, including the global distribution indicated by Δ x bin ¼ correspond to the neutral shear flow from Sec. IVA (top left), parallel shear flow from Sec. IV B (top right), perpendicular shear flow from Sec. IV C (bottom left), and turbulent flow from Sec. V (bottom right). For comparison, the relative change in the average momentum Δ h p i =p 0 is also shown (black dashed
