An Efficient Method for Computing the Power Potential of Bypass Hydropower Installations

open access: yesEnergies, 2022
Small-scale hydropower installations make possible a transition towards decentralized electrical power production with very low ecological footprint. However, the prediction of their power potential is difficult, because the incoming flow velocity and ...

Plane waves in noncommutative fluids

open access: yes, 2013
We study the dynamics of the noncommutative fuid in the Snyder space perturbatively at the first order in powers of the noncommutative parameter. The linearized noncommutative fluid dynamics is described by a system of coupled linear partial differential

Computational Fluid Dynamics for Fixed Bed Reactor Design.

open access: yesAnnual Review of Chemical and Biomolecular Engineering, 2020
Flow, heat, and mass transfer in fixed beds of catalyst particles are complex phenomena and, when combined with catalytic reactions, are multiscale in both time and space; therefore, advanced computational techniques are being applied to fixed bed ...

Adjoint-based shape optimization for the minimization of flow-induced hemolysis in biomedical applications

open access: yesEngineering Applications of Computational Fluid Mechanics, 2021
This paper reports on the derivation and implementation of a shape optimization procedure for the minimization of hemolysis induction in blood flows through biomedical devices.Despite the significant progress in relevant experimental studies, the ever ...

Experimental observation of shear thickening oscillation

open access: yes, 2013
We report experimental observation of the shear thickening oscillation, i.e. the spontaneous macroscopic oscillation in the shear flow of severe shear thickening fluid.

Nonideal Compressible Fluid Dynamics of Dense Vapors and Supercritical Fluids

open access: yesAnnual Review of Fluid Mechanics
The gas dynamics of single-phase nonreacting fluids whose thermodynamic states are close to vapor-liquid saturation, close to the vapor-liquid critical point, or in supercritical conditions differs quantitatively and qualitatively from the textbook gas ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Author Correction: Recent increases in tropical cyclone intensification rates

open access: yesNature Communications, 2019
The original version of this Article contained an error in the second sentence of the first paragraph of the ‘Quantile mapping’ section of the Methods, which incorrectly read ‘We primarily focus on results produced using an additive version of QDM26 by ...

Bridging large-scale and coastal variability to improve seasonal sea level predictions along the U.S. and Canadian West Coast

open access: yesnpj Climate and Atmospheric Science
Coastal communities are increasingly vulnerable to long-term sea level rise and fluctuations driven by climate variability. While recent advances in coupled climate models enable sea level predictions several months in advance, further efforts are needed

On the Mean Residence Time in Stochastic Lattice-Gas Models

open access: yes, 2018
A heuristic law widely used in fluid dynamics for steady flows states that the amount of a fluid in a control volume is the product of the fluid influx and the mean time that the particles of the fluid spend in the volume, or mean residence time.
