Turbulent structures, integral length scale and turbulent kinetic energy (TKE) dissipation rate in compound channel flow

, 2017
In the present study, high data rate measurements were obtained for the streamwise and vertical velocity components using 2D Laser Doppler Velocimeter. The turbulent field in a straight compound-channel flow was characterized for three different uniform ...

Mechanism and analytical methods for carbon emission-exergy flow distribution in heat-electricity integrated energy system

, 2023
The carbon emission flow (CEF) is an effective tool for tracking carbon emissions in the integrated energy system (IES). However, there are still several limitations to applying CEF to analyze the potential for carbon reduction in different energy links ...

The Flow of Energy

Physics Procedia, 2011
AbstractIn this paper, the flow of energy in materials is presented as mechanical waves with a distinct velocity or speed of transition. This speed of transition came about through the observations of cold fusion experiments, i.e., Low Energy Nuclear Reactions (LENR) and superconductor gravity experiments, both assumed speculative by mainstream science.

Assisting effect of Al2O3 on MnOx for NO catalytic oxidation

Green Energy & Environment, 2021
Various Mn-based catalysts for NO oxidation were prepared using MnOx as active compound, while TiO2 and Al2O3 were adopted as catalyst support. The performance of the catalysts was tested to study the effect of support on Mn-based catalyst activity ...

The appeal of the good life: strategies for communicating sufficiency practices and policies

Sustainability: Science, Practice, & Policy
This article examines how sufficiency, an approach to sustainability focused on reducing resource consumption, can be communicated as a pathway to a good life rather than a call to sacrifice. Based on a representative survey in Germany, the findings show
