Further experimental results on the structure and acoustics of turbulent jet flames [PDF]
, 1975 The structure of open turbulent jet flames is experimentally studied in the context of their noise emission characteristics. The differences between premixed and (co-flow) non-premixed flames are explored.

Forced Draught Impact on Externally Venting Flames: An Experimental and Numerical Investigation
Fire and Materials, EarlyView.ABSTRACT Wind can significantly influence fire development and spread in urban and forest environments causing fatal consequences for the public, the first responders, and the environment. Wind‐driven fires can have a significant impact on structural fires as wind can increase the fire's intensity, development, and flame spread.

Results of 1/4-Scale Experiments. Vapor Simulant And Liquid Jet A Tests [PDF]
, 2000 A quarter-scale engineering model of the center wing tank (CWT) of a 747-100 was constructed. This engineering model replicated the compartmentalization, passageways, and venting to the atmosphere.

Conditional moment closure modelling of soot formation in turbulent, non-premixed methane and propane flames [PDF]
, 2009 Presented are results obtained from the incorporation of a semi-empirical soot model into a first-order conditional moment closure (CMC) approach to modelling turbulent, non-premixed methane–air and propane–air flames.

Experimental and Numerical Investigation of Cedar Façade Flame Spread With Respect to Sidewall
Fire and Materials, EarlyView.ABSTRACT In response to growing energy conservation and carbon neutrality efforts, façade systems incorporating wooden materials have attracted increasing attention, which in turn raises concerns about their combustibility. This study presents a combined experimental and numerical investigation of flame spread along cedar façades.

Effects of H2O, CO2, and N2 Air Contaminants on Critical Airside Strain Rates for Extinction of Hydrogen-Air Counterflow Diffusion Flames [PDF]
Coaxial tubular opposed jet burners (OJB) were used to form dish shaped counterflow diffusion flames (CFDF), centered by opposing laminar jets of H2, N2 and both clean and contaminated air (O2/N2 mixtures) in an argon bath at 1 atm.

Fire and Materials, EarlyView.ABSTRACT Fire sources in actual compartment fires exhibit a predominantly uneven spatial distribution. In this context, the impact of the height and location of the fire source, as well as the heat release rate (HRR) of the fire, on the thermal characteristics of Externally Venting Flames (EVF) is experimentally investigated.

Filtered density functions from direct numerical simulation of a reactive jet in cross-flow
, 2010 Direct numerical simulation (DNS) with multi-step hydrogen-air chemical kinetics is used to investigate the nearfield of a flame stabilized above a reactive jet in cross-flow (JICF). JICF configurations are typically used where rapid mixing is desirable;

Flame extinction of oxy-syngas nonpremixed jet flames
, 2014 Interest in carbon capture relevant to syngas based oxy-fuel combustion has inspired an extension of the high-resolution direct numerical simulation (DNS) to investigate the comprehensive nature of oxy-syngas combustion. The current research was motivated by two observations: (1) the local flame extinction of CO2-diluted oxy-syngas combustion has not ...

A Scoping Review and Bibliometric Analysis on Smart Firefighting in Buildings and Infrastructures
Fire and Materials, EarlyView.ABSTRACT Smart Firefighting is a concept that has emerged within the fire engineering and fire science disciplines in recent years. It can enable informed decision making and improved fire safety. However, its scope, definition, outcomes, and value to emergency management remain unclear. To investigate this, a scoping review and a bibliometric analysis
