Flow structure and unsteady characteristics of fountain flow induced by dual impinging jets

open access: yesKongqi donglixue xuebao
The flow-field structure and mechanical characteristics of dual impinging jets are critical issues during the takeoff and landing phases of aircraft. However, the unsteady characteristics of the fountain effect induced by dual impinging jets have not yet

Safety of Sodium‐Ion Batteries: Evaluation and Perspective from Component Materials to Cells, Modules, and Packs

open access: yesAdvanced Energy Materials, EarlyView.
This review provides a bottom‐up evaluation of sodium‐ion battery safety, linking material degradation mechanisms, cell engineering parameters, and module/pack assembly. It emphasizes that understanding intrinsic material stability and establishing coordinated engineering control across hierarchical levels are vital for preventing degradation coupling ...

Challenges and enablers in fluidization technology

open access: yesAIChE Journal, EarlyView.
Abstract Gas–solid fluidized beds provide excellent heat and mass transfer for high‐throughput operations from coating to catalytic conversion and underpin emerging low‐carbon technologies. Yet industrial reliability, scale‐up, and control lag scientific understanding, particularly as finer, stickier, and more variable feedstocks increasingly challenge

Pre‐Curved Everting Robots With Embedded Steering Intelligence Fabricated by CO2 Laser Welding

open access: yesAdvanced Intelligent Systems, EarlyView.
Design and experimental demonstration of a laser welded growing robot for anatomically guided navigation. The robot follows an aortic arch phantom entering the branchiocephalic branch through steering by design. The figure shows the physical phantom setup, CAD defined weld geometry and full robot eversion.

Numerical Analysis of an Axisymmetric Impinging Jet in the Impingement Region.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1999
An axisymmetric impinging jet onto a flat wall has studied using a numerical model of incompressible viscous steady flow, especially close to the impingement wall. The Navier-Stokes equations are solved in terms of stream function and vorticity with the combined upwind and central finite difference method of an alternating direction implicit way ...

Pan‐Frying Conditions Affect the Tocopherol Intake From Edible Oils: Results From Temperature Measurements and the Standardized Heating of an Edible Oil

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
High temperatures in a short time on electric stoves in private homes. Fast loss of tocochromanols using standardized conditions and a miniature heating apparatus. ABSTRACT Tocochromanols (vitamin E compounds) are essential ingredients in human nutrition. Their consumption via edible oils is considered the main source of dietary intake.

Research on Heat Transfer Enhancement of Spiral Grooved Tube Heat Exchangers Based on CFD and Artificial Intelligence

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Driven by the energy crisis and carbon neutrality goals, high‐efficiency heat exchange equipment has become a core demand in the industrial sector. The spiral grooved double‐pipe heat exchanger exhibits significant heat transfer enhancement advantages, yet it requires balancing heat transfer efficiency and pressure loss.

Developmental differences in cortical bone structure in chimpanzee and human femora reflect early locomotor independence in humans

open access: yesThe Anatomical Record, EarlyView.
Abstract The cortical bone structure of long bone diaphyses changes throughout growth via skeletal modeling and has important implications for bone strength and structural integrity. Ontogenetic trends in diaphyseal structure have been identified in both chimpanzees and humans but it is not yet clear how these trends compare given notable differences ...

“They say we're a rights‐respecting school but nobody knows what that really means”: Children's rights implementation in a Scottish secondary school

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Education has been an enduring feature of international human rights law since the Universal Declaration of Human Rights in 1948 and is the only human right that is compulsory for children. Appearing in all major human rights treaties, including the UN Convention on the Rights of the Child, education is multidimensional and a multiplier of ...

Orchard netting impacts on biodiversity leading to cascading effects at the ecosystem level

open access: yesBiological Reviews, EarlyView.
ABSTRACT Agriculture must ensure food production without further compromising the ecosystem functions upon which it depends. Agricultural practices should therefore avoid harming farmland biodiversity, especially of taxa that supply the key ecosystem services (e.g.
