Quantitative Assessment of Flame Stability Through Image Processing and Spectral Analysis [PDF]

open access: yes, 2015
This paper experimentally investigates two generalized methods, i.e., a simple universal index and oscillation frequency, for the quantitative assessment of flame stability at fossil-fuel-fired furnaces.

Modeling Thermal Radiation in Combustion Environments: Progress and Challenges

open access: yesEnergies, 2023
Modeling thermal radiation in combustion environments can be extremely challenging for two main reasons. First, the radiative transfer equation (RTE), which is the cornerstone of modeling radiation in such environments, is a five-dimensional integro ...

An Autoadaptive Edge-Detection Algorithm for Flame and Fire Image Processing [PDF]

open access: yes, 2012
The determination of flame or fire edges is the process of identifying a boundary between the area where there is thermochemical reaction and those without. It is a precursor to image-based flame monitoring, early fire detection, fire evaluation, and the

Measurements of the Reynolds stress in the turbulent premixed flame

open access: yesNihon Kikai Gakkai ronbunshu, 2021
It has been shown in our previous study that the bi-modal distribution is seen in the radial component of the gas velocity obtained in the turbulent flame brush, implying that the shear component of the Reynolds stress conditioned on the unburnt mixture ...

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

open access: yes, 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.

Quantitative Analysis of Diffusion in Bursting Phenomena:

open access: yesMaketingu Janaru, 2021
When a movement occurs on the Internet, it often affects the real world. For example, “buzz,” as a positive phenomenon, and “flames,” as a negative one.

Flame Detection Method In Video Using Covariance Descriptors [PDF]

open access: yes, 2011
Video fire detection system which uses a spatio-temporal covariance matrix of video data is proposed. This system divides the video into spatio-temporal blocks and computes covariance features extracted from these blocks to detect fire.

Experimental study on premixed flame acceleration in closed pipe [PDF]

open access: yes, 2013
An experimental study has been carried out to investigate the flame acceleration in closed pipe. A horizontal steel pipe, with 2 m long and 0.1 m diameter, giving length to diameter (L/D) ratio of 20 was used in this project.

An Experimental Investigation of Flame Spreading from Bluff Body Flameholders [PDF]

open access: yes, 1958
Flame spreading from 1/16 to l inch circular cylinder flame holders in two-dimensional flow was studied experimentally. Combustion wake widths were determined by use of spark Schlieren photographs at distances up to 36 inches downstream of the flame ...
