Simulations of a Single‐Phase Flow in a Compound Parabolic Concentrator Reactor

International Journal of Photoenergy, Volume 2018, Issue 1, 2018., 2018
This paper deals with the analysis and interpretation of flow visualization and residence time distribution (RTD) in a compound parabolic concentrator (CPC) reactor using computational fluid dynamics (CFD). CFD was calculated under turbulent flow conditions solving the Reynolds averaged Navier–Stokes (RANS) equation expressed in terms of turbulent ...

Estimating the eco‐efficiency of urban waste services towards sustainable waste management

Sustainable Development, Volume 32, Issue 5, Page 5677-5691, October 2024.
Abstract Assessing the eco‐efficiency of municipalities regarding the provision of solid waste services is a useful tool for improving its sustainability. However, robust, and reliable methods are needed to benchmark the performance of municipalities. Data envelopment analysis (DEA) methods typically used to assess the eco‐efficiency of municipal solid

A Comparative Analysis of 2‐(Thiocyanomethylthio)‐Benzothiazole Degradation Using Electro‐Fenton and Anodic Oxidation on a Boron‐Doped Diamond Electrode

International Journal of Photoenergy, Volume 2018, Issue 1, 2018., 2018
2‐(Thiocyanomethylthio)‐benzothiazole (TCMTB) is used as fungicide in the paper, tannery, paint, and coatings industries, and its study is important as it is considered toxic to aquatic life. In this study, a comparison of direct anodic oxidation (AO) using a boron‐doped diamond electrode (BDD) and electro‐Fenton (EF) processes for TCMTB degradation in

Estimating the impact of carbon inefficiency and overuse of energy on the economics of water companies: A case study for England and Wales

Sustainable Development, Volume 32, Issue 4, Page 3601-3611, August 2024.
Abstract In the face of climate change, it becomes crucial to motivate action and policies within water companies towards achieving carbon neutrality. Estimating the economic consequences of inaction can be a compelling catalyst for change. In this study, the carbon inefficiency and overuse of energy among a selection of English and Welsh water ...

Rainfall and Hydrograph Styles in Ephemeral Streams of the Drylands of Patagonia (South America–Argentina)

Water Resources Research, Volume 60, Issue 8, August 2024.
Abstract Ephemeral streams in dry environments can convey high intensity sediment‐laden flash floods. The study of these events is quite difficult due to remote locations with limited accessibility, unexpected events, rough weather conditions and safety concerns.
