Flame Length of Wildland Fires: Effect of Flame Zone Depth

2022
Correlations of flame length L (or height) with the intensity of fires (kW/m2 for area sources or kW/m for line sources) have become foundational to fire behavior science (Byram 1959, Thomas 1963, Nelson and Adkins 1986, among others). Empirical data for these correlations have been based on fires fueled by wood cribs, paper strips, natural gas, and ...

Experimental investigation of flame length of buoyancy-controlled jet flames from inclined rectangular nozzles

Experimental heat transfer, 2018
In this paper, the buoyancy-controlled jet flames from the inclined rectangular nozzles with different aspect ratios have been investigated. The length-to-width aspect ratios of nozzles are 1, 2.25, 4, 9, and 16 with the same cross-sectional area.

Structure and Flame Length of Fully-Modulated, Turbulent Diffusion Flames

Combustion Science and Technology, 2000
The turbulent flame structure and flame length of fully-modulated diffusion flames was examined over a range of pulsing frequencies, injection flow rates, and duty-cycles. An injection system employing an electronically-controlled solenoid value was used to discharge puffs of unhealed natural gas and ethylene fuel into still air at one atmosphere ...

Radiative Fraction and Flame Length of Propane Jet Diffusion Flames in a Crossflow

Физика горения и взрыва, 2020
Many industrial combustion devices rely on jet flame combustion in the crossflow to achieve mixing and reaction. Previous research offers a limited predictive capability regarding the coupling effects of the crossflow and jet flow on the flame radiative fraction.

Experimental study on the maximum temperature and flame extension length driven by strong plume in a longitudinal ventilated tunnel

Experimental Thermal and Fluid Science, 2019
In order to study the maximum temperature and flame extension length when flame impinges on the tunnel ceiling, experiments were carried out with different longitudinal velocities, heat release rates and ceiling-source heights considered.
