The ignition, combustion characteristics, and cenosphere formation of single droplets four vacuum residues (VRs) from different refineries with various asphaltene contents were studied experimentally. VRs suspended at the tip a silicon carbide fiber heated in air temperatures 973 1023 K, respectively, an electrically tube furnace. ignition behavior recorded using CCD camera, which enabled deter...

There are several mechanisms that affect a gas when using discharge plasma to initiate combustion or to stabilize a flame. There are two thermal mechanisms-the homogeneous and inhomogeneous heating of the gas due to 'hot' atom thermalization and vibrational and electronic energy relaxation. The homogeneous heating causes the acceleration of the chemical reactions. The inhomogeneous heating gene...

There are many incentives to increase the fuel efficiency of combustion processes. This paper looks at two available options to achieve this goal. The former aims to develop an experimental method that can analyze combustion at extremely high pressures to improve the understanding of high pressure H2/air combustion. Experimental data has been lacking a suitable combustion diagnostic to visualiz...

Re-ignition and re-initiation mechanisms of quenched detonation waves passing over a backward facing step are investigated using a high-resolution discontinuous Galerkin method, in which the reaction chemistry is described using a detailed chemical model. A stoichiometric Hydrogen/Oxygen mixture with different diluents (Argon and Nitrogen) is considered to assess effects of the mixture composit...

A family of hydrophobic borohydride-rich ionic liquids was developed, which exhibited the shortest ignition delay times of 1.7 milliseconds and the lowest viscosity (10 mPa s) of hypergolic ionic fluids, demonstrating their great potential as faster-igniting rocket fuels to replace toxic hydrazine derivatives in liquid bipropellant formulations.

This work presents an investigation of fundamental combustion properties, specifically laminar burning velocity and ignition delay time, Alcohol-to-Jet Synthetic Paraffinic Kerosene (AtJ-SPK). Used in blends, this fuel is a sustainable aviation that consists mostly two long-chained, highly branched alkanes. Laminar velocities were measured at preheat temperature 473 K pressures 1 3 bar using th...

ISSN: 2319-1120 /V2N3: 299-309 © IJAEST Abstract— Wireless sensor network technologies normally deploy a large number of small, low cost sensors, fairly densely that can observe and influence the physical world around them by gathering physical information, transform it into electrical signals, send it to a remote location to do some analysis and deploy the results in different applications. Th...

The formation of ZnSe via a mechanically-induced self-sustaining reaction (MSR) from a Zn/Se mixture showed that only size reduction and mixing of the reactants without product formation occurred during the induction period prior to ignition. Therefore, all mechanical energy supplied by the planetary mill during this time, called the ignition time (tig), was used exclusively in the activation o...
