Spatially resolved heat release rate measurements in turbulent premixed flames
Heat release rate is a fundamental property of great importance for the theoretical and experimental elucidation of unsteady flame behaviors such as combustion noise, combustion instabilities, and pulsed combustion. Investigations of such thermoacoustic interactions require a reliable indicator of heat release rate capable of resolving spatial structures in turbulent flames. Traditionally, heat...
متن کاملSimulation of premixed turbulent flames
1. Introduction Premixed turbulent flames are of increasing practical importance and remain a significant research challenge in the combustion community. These flames have the potential to operate cleanly and efficiently over a broad range of fuels, and therefore to represent a key element in the implementation of low-emissions burners for a variety of industrial applications. However, it is di...
متن کاملTurbulent Oxygen Flames in Type Ia Supernovae
In previous studies, we examined turbulence-flame interactions in carbonburning thermonuclear flames in Type Ia supernovae. In this study, we consider turbulence-flame interactions in the trailing oxygen flames. The two aims of the paper are to examine the response of the inductive oxygen flame to intense levels of turbulence, and to explore the possibility of transition to detonation in the ox...
متن کاملInfluence of coal dust on premixed turbulent methane–air flames
This study discusses the design of a new experimental platform, the Hybrid Flame Analyzer (HFA) to measure burning velocity of gas, dust, and hybrid (gas and dust) premixed flames. The HFA is used to analyze a particle–gas–air system of coal dust particles (75–90 lm and 106–120 lm) in a premixed CH4–air (/g = 0.8, 1.0 and 1.2) flame. Experimental results show that particles usually increase the...
متن کاملEffects of Gravity on Sheared and Nonsheared Turbulent Nonpremixed Flames
The present numerical study is concerned with the fundamental physics of the multi-way interaction between turbulence, chemical reaction and buoyancy in a nonpremixed flame. The method of direct numerical simulation (DNS) is used to solve the instantaneous three-dimensional governing equations. Because of the present supercomputer limitations, we consider two simple flow geometries, namely an i...
