Algebraic models of plane Couette equilibria
arXiv:2605.31385v1 Announce Type: new Abstract: Recent computations of weakly unstable equilibria, traveling waves, and periodic orbits in transitional shear flows suggest a spatiotemporal, dynamical-systems approach to low-Reynolds turbulence. Many invariant solutions have been computed precisely using high-dimensional direct numerical simulations, but little is known about how many solutions exist, how they are organized, or which sets of solutions best characterize the flow. In this paper...
Turbulence: An Entropic Approach
arXiv:2606.03139v1 Announce Type: new Abstract: We show that maximizing the generalized entropic functional $S_{q,\delta}$ subject to standard kinetic energy constraints provides generalized canonical distributions that agree perfectly with measured probability densities of velocity differences at distance $r$ in highly-turbulent Taylor-Couette flow. The end point of the turbulent cascade is described by $\delta =\frac{3}{2}$, a parameter value that also plays an important role in black-hole...
