Sustainable Thermal Solutions: Enhancing Heat Transfer with Turbulators and Nanofluids

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Nanofluids, which are nanoparticle suspensions in base fluid, facilitate heat transmission due to their improved thermal conductivity. Turbulators, which are inserts into fluid flow channels, disturb the flow, increasing turbulence and hence the heat transfer rate.

3D finite element simulations of reinforced concrete elements exposed to fire [PDF]

open access: yes, 2017
Fire could dramatically reduce strength of reinforced concrete elements and it is considered one of the major threats for the structural safety of buildings: structural members may even collapse due to intensity and duration of fire.

The Environmental Emission and Climate Change Impact of Hydrogen Fuel Derived from Photocatalysis Water‐Splitting Reaction

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
In this works, life cycle analysis (LCA) of photocatalysis hydrogen synthesis reaction based on a pilot scale system is presented. Through the LCA, it is shown that majority of the carbon emission of the process is contributed by photocatalyst synthesis process and the use of sacrificial reagent in the photocatalytic hydrogen evolution reaction ...

Putting climate change at the heart of education: Is England's strategy a placebo for policy?

open access: yesBritish Educational Research Journal, Volume 48, Issue 6, Page 1083-1101, December 2022., 2022
Abstract In this paper we present an analysis of the sustainability and climate change strategy for education and children's services systems in England, produced by the Department for Education. Using critical discourse analysis, we juxtapose qualitative data collected from >200 youth teachers and teacher educators in the context of co‐creating a ...

Hysteresis Behavior of RC Beam–Column Joints of Existing Substandard RC Structures Subjected to Seismic Loading–Experimental and Analytical Investigation

open access: yesBuildings
Four exterior reinforced concrete beam–column joint subassemblages with poor reinforcement details and low-quality materials were constructed and subjected to cyclic lateral deformations under constant axial loading of the columns.

A health(y) subject? Examining discourses of health in physical education curricula across the UK

open access: yesBritish Educational Research Journal, Volume 48, Issue 6, Page 1161-1182, December 2022., 2022
Abstract In this paper, we present the findings from our critical analysis of the health discourses evident with physical education (PE) curricula in each UK home nation—England, Northern Ireland, Scotland and Wales. We carried out a critical discourse analysis of those curriculum documents that talk directly to PE teachers about how to organise, enact

A fracture-mechanics model for debonding of external fibre reinforced polymer plates on reinforced concrete beams

open access: yes, 2006
A Fracture-mechanics model for debonding of external fibre reinforced polymer plates on reinforced concrete beams is presented. The conventional methods of concrete-FRP interface analysis use finite element models, which require details of unknown and ...
