Fluid dynamics and epidemiology: Seasonality and transmission dynamics
The Physics of Fluids, 2021 Epidemic models do not account for the effects of climate conditions on the transmission dynamics of viruses. This study presents the vital relationship between weather seasonality, airborne virus transmission, and pandemic outbreaks over a whole year ...

Editorial: Mathematical problems in physical fluid dynamics: part I
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2022 Fluid dynamics is a research area lying at the crossroads of physics and applied mathematics with an ever-expanding range of applications in natural sciences and engineering. However, despite decades of concerted research efforts, this area abounds with many fundamental questions that still remain unanswered.

Fluid dynamics beyond the continuum: A physical perspective on large-eddy simulation [PDF]
Physical Review Fluids, 2021 In this work, we will present a physically consistent theory to derive the governing equations of the Large Eddy Simulation (LES) framework based on first principles rather than the motivation to conduct computationally affordable simulations of turbulent flows.

Where surface physics and fluid dynamics meet: Rupture of an amphiphile layer by fluid flow [PDF]
The Journal of Chemical Physics, 2006 We investigate the fluctuating pattern created by a jet of fluid impingent upon an amphiphile-covered surface. This microscopically thin layer is initially covered with 50μm floating particles so that the layer can be visualized. A vertical jet of water located below the surface and directed upward drives a hole in this layer. The hole is particle-free

Bianchi Type I Universes with Causal Bulk Viscous Cosmological Fluid [PDF]
, 2001 We consider the dynamics of a causal bulk viscous cosmological fluid filled constantly decelerating Bianchi type I space-time. The matter component of the Universe is assumed to satisfy a linear barotropic equation of state and the state equation of the ...

A Physically-Motivated Deformable Model Based on Fluid Dynamics [PDF]
, 2006 A novel deformable model for image segmentation and shape recovery is presented. The model is inspired by fluid dynamics and is based on a flooding simulation similar to the watershed paradigm. Unlike most watershed methods, our model has a continuous formulation, being described by two partial differential equations.

Dynamics of Relativistic Magnetized Blast Waves [PDF]
, 2001 The dynamics of a relativistic blast wave propagating through magnetized medium is considered taking into account possible inhomogeneities of density and magnetic field and additional energy supply.

Experience report of physics-informed neural networks in fluid simulations: pitfalls and frustration [PDF]
SciPy, 2022 Though PINNs (physics-informed neural networks) are now deemed as a complement to traditional CFD (computational fluid dynamics) solvers rather than a replacement, their ability to solve the Navier-Stokes equations without given data is still of great ...
