Flame length of buoyant turbulent slot flame

Proceedings of the Combustion Institute, 2019
Abstract This work presents a modeling and experimental analysis on the flame length of buoyant turbulent slot diffusion flame. An approximate predictive correlation of flame length is derived based on the governing equations. The role of initial momentum and buoyancy on flame length is quantitatively described by a modified Froude number Frm.

An investigation of the detailed flame shape and flame length under the ceiling of a channel

Proceedings of the Combustion Institute, 2015
Abstract This paper presents an experimental investigation on the flame shape and length under the ceiling of a channel, and altogether 48 experiments with four experimental setups were performed. The experimental setups include fires in the open space, flush with a wall without ceiling, at the longitudinal centerline of a channel and flush with the ...

On the flame length in firewhirls with strong vorticity

Combustion and Flame, 2013
The influence of strong rotation on the flame length in firewhirls (normalized by the fuel supply rate) is investigated analytically. A new prediction for the length of the flame in firewhirls with strong rotation is obtained by introducing the compensating regime of vortical flows. The prediction is in a good agreement with experimental results.

The Impact of Biomass Cofiring on Volatile Flame Length

Energy & Fuels, 2013
The physical characteristics and composition of biomass can vary significantly from coal and from one fuel to another, and these differences can impact the structure of the resulting pulverized fuel flame, particularly the volatile flame. The length and location of the volatile flame, which is the zone dominated by the combustion of volatiles, is ...

Corrigendum to: Interdependencies between flame length and fireline intensity in predicting crown fire initiation and crown scorch height

International journal of wildland fire, 2021
This state-of-knowledge review examines some of the underlying assumptions and limitations associated with the inter-relationships among four widely used descriptors of surface fire behaviour and post-fire impacts in wildland fire science and management,

The curvature Markstein length and the definition of flame displacement speed for stationary spherical flames

Proceedings of the Combustion Institute, 2015
Abstract The separate effects of flame stretch and flame curvature are investigated in the present study considering a stationary spherical flame configuration that experiences no stretch but has a finite curvature. A theoretical expression for the flame displacement speed, derived from asymptotic analysis, is compared with numerical simulations ...

Prediction of Flame Length in Opposed-Flow Flame Spread: Global Similarity Analysis and Experiments

Combustion Science and Technology, 2021
Opposed-flow flame spread over solid fuels is an important case of fire safety studies. Spread rate and flame structure depend on fuel nature and burning conditions, and they can be used to study material flammability and fundamental combustion ...
