Food, Energy, and Health Implications of Agrivoltaic Farms

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract The benefits of agrivoltaics (AV) are documented, with empirical evidence for their suitability for collocated energy generation, crop cultivation, and water savings, even for staple crops. What is lacking is a holistic modeling framework to design and optimize AV systems for specific crop types, micro‐environments, and panel configurations ...

Vertical Momentum Flux at 0°N, 140°W: Unresolved Internal Waves and Implications for Cold Tongue SST

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract The Equatorial Pacific Cold Tongue is critical to the Bjerknes feedback driving the El Niño‐Southern Oscillation (ENSO), yet simulating Cold Tongue sea surface temperature (SST) remains difficult. Historical turbulence observations reveal a vertical momentum flux deficit in the zonal momentum budget at 0°N, 140°W.

Physics‐Informed Machine Learning Framework to Retroactively Estimate Mantle Thermal Convection From Partial Geophysical Observations

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Mantle convection drives the solid Earth, powering plate motions, volcanism, and earthquakes while regulating planetary heat loss. Reconstructing its history is hampered by sparse, noisy observations concentrated near the surface and the present day. Here I develop an inverse physics‐informed neural network framework to estimate mantle thermal

Introducing the Coincidence Index: A Novel Diagnostic and Production‐Based Framework for Water Body Interaction Analysis and Its Application to Study the Interaction of River Plumes

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Quantifying interactions between distinct water bodies is critical yet challenging for understanding ocean and estuarine dynamics. We introduce the coincidence index (CI), defined as the product of two arbitrary tracers (a $a$, b $b$), to diagnose where two water masses coexist and mix.

Hydrodynamics of the Cylinder Rotating in the Unbounded Viscous Medium

Механика машин, механизмов и материалов, 2009
It is shown, that at first a laminar flow around rotating cylinder with growth of Reynolds number passes into a pseudo-laminar flow, and then into a steady turbulent flow.

Variable Turbulent Schmidt and Prandtl Number Modeling

Engineering Applications of Computational Fluid Mechanics, 2010
Abstract:This paper describes variable turbulent Schmidt and Prandtl number formulations, based on Rodi’s (1980) algebraic Reynolds stress model adapted to velocity-scalar correlations. Since the approach is algebraic in nature, it does not introduce transport equations beyond the ones already existing to compute the flow, rendering it a viable ...

A TURBULENT HEAT FLUX TWO–EQUATION θ 02 –εθ CLOSURE BASED ON THE V 2F TURBULENCE MODEL

TASK Quarterly, 2003
The paper deals with the proposition of a two-equation turbulent heat flux closure without any damping function. The model has been based on Durbin’s V 2F dynamic turbulence closure and the Deng-Wu-Xi thermal turbulence model.

Ambipolar diffusion in large Prandtl number turbulence [PDF]

Monthly Notices of the Royal Astronomical Society, 2019
ABSTRACT We study the effects of ambipolar diffusion (AD) on hydromagnetic turbulence. We consider the regime of large magnetic Prandtl number, relevant to the interstellar medium. In most of the cases, we use the single-fluid approximation where the drift velocity between charged and neutral particles is proportional to the Lorentz ...

A Similarity Solution with Two-Equation Turbulence Model for Computation of Turbulent Film Condensation on a Vertical Surface

Journal of Applied Fluid Mechanics, 2018
In this paper, we presented a similarity solution for turbulent film condensation of stationary vapor on an isothermal vertical flat plate. In this method, some similarity transformations are employed and the set of governing partial differential ...

Asymptotic Behaviour of Galactic Small-scale Dynamos at Modest Magnetic Prandtl Number

The Astrophysical Journal Letters
Magnetic fields are critical at many scales to galactic dynamics and structure, including multiphase pressure balance, dust processing, and star formation. Dynamo action determines their dynamical structure and strength.
