Statistically self-similar mixing by Gaussian random fields
Michele Coti Zelati, Theodore D. Drivas, Rishabh S. Gvalani
We study the passive transport of a scalar field by a spatially smooth but white-in-time incompressible Gaussian random velocity field on . If the velocity field …
The Feynman-Lagerstrom criterion for boundary layers
Theodore D. Drivas, Sameer Iyer, Trinh T. Nguyen
We study the boundary layer theory for slightly viscous stationary flows forced by an imposed slip velocity at the boundary. According to the theory of Prandtl (1904) and Batchelor…
On the large-scale sweeping of small-scale eddies in turbulence -- A filtering approach
Theodore D. Drivas, Perry L. Johnson, Cristian C. Lalescu +1
We present an analysis of the Navier-Stokes equations based on a spatial filtering technique to elucidate the multi-scale nature of fully developed turbulence. In particular, the a…
Islands in stable fluid equilibria
Theodore D. Drivas, Daniel Ginsberg
We prove that stable fluid equilibria with trivial homology on curved, reflection-symmetric periodic channels must posses "islands", or cat's eye vortices. In this way, arbitrarily…
Twisting in Hamiltonian Flows and Perfect Fluids
Theodore D. Drivas, Tarek M. Elgindi, In-Jee Jeong
We introduce a notion of stability for non-autonomous Hamiltonian flows on two-dimensional annular surfaces. This notion of stability is designed to capture the sustained twisting…
On the Support of Anomalous Dissipation Measures
Luigi De Rosa, Theodore D. Drivas, Marco Inversi
By means of a unifying measure-theoretic approach, we establish lower bounds on the Hausdorff dimension of the space-time set which can support anomalous dissipation for weak solut…
