Large Eddy Simulation of Autoignition in a Turbulent Hydrogen Jet Flame Using a Progress Variable Approach

Journal of Combustion, 2012
The potential of a progress variable formulation for predicting autoignition and subsequent kernel development in a nonpremixed jet flame is explored in the LES (Large Eddy Simulation) context. The chemistry is tabulated as a function of mixture fraction

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 ...

MILD pulverized combustion technology: The latest research progress and key scientific issues

Meitan xuebao
The MILD combustion is a combustion mode that occurs in a moderate or extremely low oxygen environment, combining the advantages of high combustion heat utilization and very low NOx emissions, and is considered by the international combustion field to be

Prechamber selection for a two stage turbulent jet ignition of lean air-gas mixtures for better economy and emission

E3S Web of Conferences, 2018
The paper presents the results of thermodynamic and exhaust emission analyses of the combustion process using three combustion chambers. The combustion process research was performed on a single-cylinder AVL 5804 engine equipped with a dual-band ...

Success and failure in foreign policy: Comparing Bob Hawke and Kevin Rudd's regional order‐building initiatives

Australian Journal of Public Administration, EarlyView.
Abstract Remarkably little is known about what factors drive success or failure in foreign policy. In part, this is because there is little fundamental agreement on what constitutes success or failure in this domain in the first place. This article engages with these shortcomings by comparing two similar regional order‐building initiatives overseen by ...

Numerical simulation of reacting and non-reacting liquid jets in supersonic crossflow

Applications in Energy and Combustion Science
Canonical jet in supersonic crossflow (JISC) studies have been widely used to study fundamental physics relevant to a variety of applications. While most JISC works have considered injection of gases, liquid injection is also of practical interest and ...

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 ...

/Air Mixture by a Pre-Chamber-Initiated Turbulent Jet

, 2020
To provide insights into the fundamental characteristics of pre-chamber combustion engines, the ignition of lean premixed CH4/air due to hot gas jets initiated by a passive narrow throated pre-chamber in a heavy-duty engine was studied computationally. A

Five Principles for a New Economic Consensus

Global Policy, EarlyView.
ABSTRACT This paper puts forward five principles for a new economic consensus, which could serve as a modern alternative to the Washington Consensus of 35 years ago. They are built on new ideas that have gained currency in economics over the past three decades. We also provide examples of the policies that could follow from these principles.

Modelling of turbulent swirling flows [PDF]

, 2004
This thesis investigates the predictability of non-reacting and reacting anistropic turbulent, swirling flows using popular turbulence models with a robust numrical procedure. The performance of these turbulence models is assessed and compared against
