One complete set of measurements was made upstream of curvature in the unperturbed boundary layer, and this constituted a reference set. The perturbations were assumed to be of sufficiently short wavelengths to justify the slow time and radiusfrozen-in approximation for the unperturbed systems. In this latter case, one regards (3.1)-(3.3) as generating unperturbed bulk solutions which shall drive the perturbed modes seen as test modes. Thus, surprisingly, the long-term relaxation from stabilizing curvature resulted in increased turbulent mixing, compared to the unperturbed boundary layer. The analysis of ribbing necessarily starts from a mathematical description of the unperturbed base state, a steady, two-dimensional viscous freesurface flow. The unperturbed dipole initially propagates along the x-axis with = 0 and = 0. The front of the drop always regains its unperturbed spherical shape. For the constant velocity piston, the perturbation particle velocity a t the unperturbed piston location is zero. We assume that the unperturbed plasma is neutral. It is convenient to transform the equation to a reduced-variables coordinate system moving with the unperturbed soliton. The mixing region, of course, does not exist for the unperturbed case. Again, their recovery to the unperturbed condition is slow and consistent with other results discussed above. In what follows, the subscript '0' indicates an unperturbed quantity. Results have been presented only for the case when the unperturbed configuration is plane. These examples are from corpora and from sources on the web.
