Large-scale energy spectra in surface quasi-geostrophic turbulence

, 2004
The large-scale energy spectrum in two-dimensional turbulence governed by the surface quasi-geostrophic (SQG) equation $$\partial_t(-\Delta)^{1/2}\psi+J(\psi,(-\Delta)^{1/2}\psi) =\mu\Delta\psi+f$$ is studied.

Multi‐Objective Optimization of Phase Change Coupled Thermal Management System Based on NSWOA

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
NSWOA‐optimized liquid‐PCM hybrid cooling reduces 18 650 pack Tmax by 5.9 K and ΔT to 4.7 K at 4 °C discharge, validated within 1.5 K error; non‐uniform cell placement and key PCM properties are balanced for safety. This study investigates phase change materials (PCMs) for lithium battery thermal management.

Inertial range turbulence in kinetic plasmas

, 2007
The transfer of turbulent energy through an inertial range from the driving scale to dissipative scales in a kinetic plasma followed by the conversion of this energy into heat is a fundamental plasma physics process.

Bio‐Inspired Ordered WO3 Nano‐Helixes Enable Multi‐Band Electrochromic Smart Windows with Ultrafast Switching and Robust Cyclability

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Biomimetic ordered nano‐helix WO3 films enable multi‐band electrochromic photothermal management across the visible, near‐infrared, mid‐ and long‐wave infrared spectra, with ultrafast switching (<3 s) and robust durability (>10 000 cycles). These findings establish new paradigms for next‐generation photothermal management systems and energy‐efficient ...

Optimizing a Straight‐Bladed Vertical Axis Wind Turbine With Computational Fluid Dynamics (CFD), Artificial Neural Network (ANN), and Genetic Algorithm (GA)

Energy Science &Engineering, EarlyView.
ABSTRACT Vertical axis wind turbine (VAWT) is a suitable renewable power generation tool for use in urban areas, especially at low wind speeds and with low noise level. However, an approach with accurate results, acceptable time consumption, and cost for optimizing this turbine is not reported in the literature.
