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 ...

Geometrical Effects on Flame Spread Rate for Wildland Fine Fuels

Combustion Science and Technology, 1993
Abstract It has long been common practice for firefighters to test wildfire potential by lighting single strands or leaves (sheltered from the wind) and observing the rate of spread. This paper discusses single-element fire spread and its potential as a method for determining fine- fuel moisture content and for estimating the likely rate of spread ...

Influence of Fuel-Air Ratio on Horizontal Flame Spread Rates

Heat Transfer: Volume 2, 1997
Abstract Flame spread along horizontal surfaces in the presence of a forced convective airflow depends primarily upon the transfer of radiant energy to downstream surfaces from a flame front that is tilted in the direction of flow. The soot in the flame serves as the primary source of radiation but the soot that emerges from the flame ...

Correlating Downward Flame Spread Rates for Thick Fuel Beds

Combustion Science and Technology, 1983
Flame spread rates are presented for polymethylmethacrylate fuel beds as a function of gravitational acceleration and ambient pressure and oxygen concentration. The data are correlated by plotting a dimensionless spread rate that is a measure of the heat transferred forward of the flame, required to sustain the flame, compared to the maximum possible ...

Investigation of the structure and spread rate of flames over PMMA slabs

Applied Thermal Engineering, 2018
Abstract Experimental and numerical investigations of upward and downward flame spread over flat polymethyl methacrylate (PMMA) slabs are presented here. Experiments have been carried out using PMMA slabs of different thickness in the range of 1.6 mm–5.4 mm.

Estimation of heat release rate based on analysis of flame spread behavior in mattresses

Fire and Materials, 2023
AbstractTo investigate the fire danger of mattresses, combustion experiments were conducted with a mattress installed at different heights above the floor to better understand their combustion behavior. The installation height was varied because the height of a mattress varies depending on the bed frame, and the combustion behavior is expected to ...

Exploring fire response to high wind speeds: fire rate of spread, energy release and flame residence time from fires burned in pine needle beds under winds up to 27 ms−1

, 2020
The relationship between wildland fire spread rate and wind has been a topic of study for over a century, but few laboratory studies report measurements in controlled winds exceeding 5 m s−1.

Prediction of the steady flame spread rate by the principle of minimal entropy production

Combustion Theory and Modelling, 1999
The propagation of a two-dimensional diffusive flame over a combustible material is studied by solving steady-state conservation equations written in the coordinate system fixed on the flame front. The analysis of a two-dimensional problem featuring flame spread rate as an eigenvalue has shown that there is no unique solution relative to the flame ...

Effect of transverse flow on flame spread and extinction over polyethylene-insulated wires

, 2020
The spread of flames over solid combustible surface in a transverse flow (perpendicular to the flame spread direction) is common in real fire scenarios, but has not been well quantified yet.
