Detailed radiation modeling of two flames relevant to fire simulation using Photon Monte Carlo - Line by Line radiation model

September 5, 2024
Author(s)
Chandan Paul, Somesh Roy, Johannes Sailer, Fabian Braennstroem, Mohamed Ahmed, Arnaud Trouve, Hadi Bordbar, Simo Hostikka, Randall J. McDermott
This work reports benchmark data sets for radiative heat transfer in two distinct fire configurations obtained from the Measurement and Computation of Fire Phenomena (MaCFP) working group database. The cases include a 19.2 kW non-sooting turbulent methanol

A Simple Two-Step Reaction Scheme for Soot and CO

May 23, 2022
Author(s)
Kevin B. McGrattan, Randall J. McDermott, Jason E. Floyd
A relatively simple two-step combustion model is proposed for predicting soot and CO generation in under-ventilated fire simulations. The scheme consists of two mixing-controlled reaction steps performed in series. Validation calculations are described

Modeling flame extinction and reignition in large eddy simulations with fast chemistry

May 16, 2017
Author(s)
James White, Sebastien Vilfayeau, Andre Marshall, Arnaud Trouve, Randall McDermott
This work seeks to support the validation of large eddy simulation (LES) models used to simulate the response of fires to the activation of a suppression system. The emphasis in the present study is on the prediction of flame weakening and extinction when

Enforcing realizability in explicit multi-component species transport

October 5, 2015
Author(s)
Randall J. McDermott, Kevin B. McGrattan, Jason Floyd
A strategy is proposed to guarantee realizability of species mass fractions in explicit time integration of the partial differential equations governing fire dynamics, which is multi-component transport problem. For a mixture of $n$ species, the

Fire Modeling for the Fire Research, Fire Protection, and Fire Service Communities

September 8, 2014
Author(s)
Kevin B. McGrattan, Randall J. McDermott, Glenn P. Forney, Kristopher J. Overholt, Craig G. Weinschenk, Jason E. Floyd
The Fire Dynamics Simulator (FDS) was first publicly released in 2000, and it has recently undergone its fifth major revision. Since its first release, FDS has been applied in three major areas: basic research in fire dynamics, performance-based design

Quantitative Infrared Imaging of Impinging Turbulent Buoyant Diffusion Flames

July 2, 2014
Author(s)
Randall J. McDermott, Ashish Newale, Brent Rankin, Harshad Lalit, Jay P. Gore
Radiation from buoyant diffusion flames with and without impingement on a flat plate is studied using a unique quantitative comparison of measured and simulated images. The coupling between the stagnation boundary layer and upstream buoyant shear layer
