Numerical Investigation of Flow Structures and Combustion Mechanisms with Different Injection Locations in a Hydrogen-Fueled Scramjet Combustor

Fire
This work primarily focuses on a three-dimensional model of flame propagation and stable combustion in a scramjet chamber. The one-equation LES turbulence model is adopted to close the sub-grid-scale turbulent viscosity terms.

Pasture feeding improves the fatty acid composition of lamb muscle

Grassland Research, EarlyView.
The diet of lambs influences the nutritional quality of their meat. This study showed that pasture‐fed lamb contained significantly higher concentrations of beneficial omega‐3 fatty acids than lamb finished on concentrate diets. These long‐chain omega‐3 fatty acids are associated with improved cardiovascular health and other health benefits.

Infrared Spectroscopic Predictions of Soil Properties for Agricultural Monitoring: Statistical and Soil Spectroscopic Considerations

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Pseudo‐independent validation (PIV) using regional datasets is common in visible‐to‐near‐infrared (vis–NIR) and mid‐infrared (MIR) spectroscopy studies and produces accurate predictions but is relevant only to regional‐scale monitoring of known sites.

Mycotoxin management in the cereal supply chain: Advanced detection, detoxification, and smart packaging strategies

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Mycotoxins remain a persistent threat to the safety and quality of cereal grains and other agricultural products, and their impact on human health continues to raise global concerns. In many situations, the practices traditionally used to control these toxins are no longer sufficiently effective. They can be costly, difficult to implement on a

Research on the Energy Conversion Mechanism of Engine Speed, Turbulence and Combustion Stability Based on Large Eddy Simulation

Energies
Cycle-to-cycle variation (CCV) is an inherent phenomenon in internal combustion engines that poses significant limitations on thermal efficiency in energy conversion. This variation can also cause structural damage.

Reducing the use of Fossil Carbon and Fuels to Defossilize the Electric Steelmaking Route: Evaluation of the Effects of Alternative C‐Bearing Materials and Hydrogen in the Electric Arc Furnace

steel research international, EarlyView.
The experiments and simulations demonstrate that, in general, alternative carbon sources can decrease fossil CO2 without adversely impacting EAF process and product. High plastics and tires ratios cause unsafe conditions and poor slag foaming. Hydrogen in EAF burners decreases CO2 but increases water vapor, which can raise the hydrogen content in ...

Ignition characteristics of hydrogen-enriched ammonia/air mixtures

Applications in Energy and Combustion Science
Ammonia is an attractive hydrogen carrier and potential fuel which could play a role in decarbonizing process heat, power or transport applications. However, the combustion properties of ammonia are disadvantageous for many technical processes.
