Abstract
Using a multiple scale method for the Taylor-Couette instability, we obtain, in a suitable moving frame, a diffusion equation for the phase variable of the vortex system. The transversal diffusion coefficient D⟩ is found to be positive. The phase diffusion equation restricted to the one-dimensional case seems to be relevant for interpreting Snyder's experiments on the relaxation of vortex systems in the Taylor-Couette flowKeywords
