Advanced Functional Materials for Marine Energy Utilization

Interdisciplinary Materials, EarlyView.
Marine renewable energy is an important future clean energy supply. We construct and sort out the material system for marine energy capture and conversion, transmission, storage, and utilization for the first time. ABSTRACT Several features of marine energy, including large reserves, sustainable utilization, environmental friendliness, make it a ...

Thermomechanical Validation of an Additively Manufactured Test Chamber for Sustainable Aviation Fuel Atomization in Jet‐In‐Crossflow Conditions

Macromolecular Symposia, EarlyView.
ABSTRACT This study aims to validate the structural and thermomechanical reliability of an additively manufactured test chamber specifically designed for the experimental investigation of sustainable aviation fuel (SAF) atomization under jet‐in‐crossflow (JICF) conditions representative of gas turbine afterburners. The proposed test chamber is designed

Flow Field of Turbulent Premixed Combustion in a Cyclone-Jet Combustor

Journal of Thermal Science and Technology, 2007
The flow field in highly turbulent premixed combustion has been examined, using a cyclone-jet combustor. The shear-strain rate is obtained by PIV system. Results show that, in combustion field, mean axial velocity does not decay along center axis and RMS

Oxide Scale Morphology of Carbon Steels Under Novel Reheating Conditions

steel research international, EarlyView.
This study focuses on the changes in oxide scale morphology formed under simulated hydrogen and oxy‐fuel reheating gas atmospheres in comparison to natural gas‐air reheating. Several different properties were analyzed, such as pore structure, ratios of iron oxides, adhesion, and distribution of alloying elements.

Thermal Degradation and Thermal Decomposition of Plasticized PVC Including POSS Additives for PVC Compounds: Mechanisms, Impact, and Performance of Standards

Journal of Vinyl and Additive Technology, EarlyView.
Additives' structures. ABSTRACT Poly(vinyl chloride) has been a key polymeric material since its commercial production in 1931, demonstrating versatility across numerous industries due to its compatibility with various additives. PVC's inherent properties, flame retardance, durability, and recyclability make it ideal for building and construction ...

The Gender of Fossil Fuels: Oil and Domestic Perils in Mandate Palestine

Gender &History, EarlyView.
ABSTRACT This article explores the gender dynamics behind the rise of kerosene – an oil derivative – as the main domestic fuel in Mandate Palestine. It argues that these dynamics were constitutive in determining who began to use oil, where and for what purposes, in turn demonstrating that women in Palestine were the promoters and targets of a campaign ...

Measurement of turbulent flame speed of natural gas/air mixtures at elevated pressure [PDF]

, 2010
Turbulent flame speeds were measured over a range of pressures to 0.8 MPa using a jet flow apparatus fired with a synthetic mixture representing a mid-European natural gas. The equivalence ratio empty set was 0.9.
