Method to Determine the Electrical Energy for Ignition of Electro-Explosive Devices

Journal of Aerospace Technology and Management, 2015
During field trials, it was observed that the delay of ignition of electro-explosive devices (EED) depends on ratings of power supplies or dynamo and also on the firing cable lengths.

Fast, non-diffusive ignition of a gaseous reacting mixture subject to a point energy source [PDF]

, 2001
The ignition of a gaseous reactive mixture subject to a localized energy source is analysed using large activation energy asymptotics. The energy released by the source results in a thermal non-uniformity in a small región of the gas.

Prompt Beta Spectroscopy as a Diagnostic for Mix in Ignited NIF Capsules

, 2004
The National Ignition Facility (NIF) technology is designed to drive deuterium-tritium (DT) internal confinement fusion (ICF) targets to ignition using indirect radiation from laser beam energy captured in a hohlraum.

A Fast Method for Selecting Bio Sourced Materials of Interest in a Candle Formulation

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT As consumer demand shifts towards more sustainable and nontoxic alternatives, the candle industry is exploring unconventional bio‐based and recycled materials as substitutes for paraffin. Four raw materials, that is rice bran wax (RBW), sugarcane wax (SCW), hydrogenated rapeseed oil (HRO), and waste cooking oil (WCO) were assessed based on ...

Analysis of Energy Transfer in the Ignition System for High-Speed Combustion Engines

Energies
In order to produce reliable and reproducible ignition of lean fuel–air mixtures and highly stratified mixtures, it is necessary to ensure a high concentration of spark discharge energy and to provide a strong energy impulse for the triggering of chain ...

Combustion characteristics in the transition region of liquid fuel sprays [PDF]

A number of important effects have been observed in the droplet size transition region in spray combustion systems. In this region, where the mechanism of flame propagation is transformed from diffusive to premixed dominated combustion, the following ...

Is it appropriate to model turbidity currents with the three-equation model?

, 2015
The three-equation model (TEM) was developed in the 1980s to model turbidity currents (TCs) and has been widely used ever since. However, its physical justification was questioned because self-accelerating TCs simulated with the steady TEM seemed to ...

High-Energy-Density Material with Magnetically Modulated Ignition

Journal of the American Chemical Society
Preparation of a redox-frustrated high-energy-density energetic material is achieved by gentle protolysis of Mn[N(SiMe3)2]2 with the perchlorate salt of the tetrazolamide [H2NtBuMeTz]ClO4 (Tz = tetrazole), yielding the Mn6N6 hexagonal prismatic cluster, Mn6(μ3-NTztBuMe)6(ClO4)6.

Performance Investigation of Eco‐Friendly Refrigerant Mixtures as an Alternative to R134a in Vapour‐Compression Refrigeration System

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The growing impacts of climate change and energy scarcity demand environmentally sustainable refrigeration solutions. This study investigates eco‐friendly refrigerants (R152a, R290 and R600a) and their optimized ternary mixture as alternatives to R134a. Four blend compositions were analysed using experimental testing and REFPROP 10.0 modelling
