How Fluid Pseudoplasticity and Elasticity Affect Propeller Flows in Biogas Fermenters
Chemie Ingenieur Technik, Volume 96, Issue 12, Page 1570-1584, December 2024.The effects of shear‐thinning and elastic rheology on propeller flows in biogas fermenters is examined via computational fluid dynamic simulations. Elastic normal stresses increase pumping rates in the laminar regime and suppress the formation of axial propeller jets. The results indicate that elasticity is critical for an accurate modeling of flows of

A Perspective on Non‐Local Electronic Transport in Metals: Viscous, Ballistic, and Beyond
Annalen der Physik, Volume 536, Issue 9, September 2024.Over the last decade, materials and technique developments have enabled a host of measurements of electronic transport on length scales shorter than the electronic mean free path. The conceptual framework for understanding these measurements is only now catching up to this rapid experimental progress. This article highlights some conceptual issues that

Asymptotic stability for the Couette flow in the 2D Euler equations
, 2013 In this expository note we discuss our recent work [arXiv:1306.5028] on the nonlinear asymptotic stability of shear flows in the 2D Euler equations of ideal, incompressible flow.

A note on “Taylor–Couette flow of a generalized second grade fluid due to a constant couple”
Nonlinear Analysis, 2010 In this brief note, we show that the unsteady flow of a generalized second grade fluid due to a constant couple, as well as the similar flow of Newtonian and ordinary second grade fluids, ultimately becomes steady.

Superstatistical Brownian motion
, 2005 As a main example for the superstatistics approach, we study a Brownian particle moving in a d-dimensional inhomogeneous environment with macroscopic temperature fluctuations. We discuss the average occupation time of the particle in spatial cells with a

Taylor dispersion and phase mixing in the non‐cutoff Boltzmann equation on the whole space
Proceedings of the London Mathematical Society, Volume 129, Issue 1, July 2024.Abstract In this paper we describe the long‐time behavior of the non‐cutoff Boltzmann equation with soft potentials near a global Maxwellian background on the whole space in the weakly collisional limit (that is, infinite Knudsen number 1/ν→∞$1/\nu \rightarrow \infty$). Specifically, we prove that for initial data sufficiently small (independent of the

About the oscillatory possibilities of the dynamical systems
, 2012 This paper attempts to make feasible the evolutionary emergence of novelty in a supposedly deterministic world which behavior is associated with those of the mathematical dynamical systems. The work was motivated by the observation of complex oscillatory

Bringing Statistics to Storylines: Rare Event Sampling for Sudden, Transient Extreme Events
Journal of Advances in Modeling Earth Systems, Volume 16, Issue 6, June 2024.Abstract A leading goal for climate science and weather risk management is to accurately model both the physics and statistics of extreme events. These two goals are fundamentally at odds: the higher a computational model's resolution, the more expensive are the ensembles needed to capture accurate statistics in the tail of the distribution.
