Practical CFD Simulations of Wind Tunnel Tests

December 1, 2013
Author(s)
Dilip K. Banerjee, Scott Hemley, Randall J. McDermott, Donghun Yeo, Marc L. Levitan
Computational fluid dynamics (CFD) has the potential of replacing wind tunnel testing in many wind engineering applications. Validated CFD software could enable structural engineers and builders to calculate wind effects on buildings for which no

Fire Dynamics Simulator Users Guide, Sixth Edition

November 4, 2013
Author(s)
Kevin B. McGrattan, Randall J. McDermott, Craig G. Weinschenk, Glenn P. Forney
This Guide describes how to use the Fire Dynamics Simulator (FDS), a software package used to simulate the impact of fire on buildings.

Fire Dynamics Simulator, Technical Reference Guide, Sixth Edition

November 4, 2013
Author(s)
Kevin B. McGrattan, Randall J. McDermott, Craig G. Weinschenk, Glenn P. Forney
This document provides the theoretical basis for the Fire Dynamics Simulator (FDS), following the general framework set forth in the “Standard Guide for Evaluating the Predictive Capability of Deterministic Fire Models,” ASTM E 1355. It is a four volume

CFD Modeling of Fire

January 11, 2012
Author(s)
Kevin B. McGrattan, Randall J. McDermott, Glenn P. Forney, Jason E. Floyd, Simo A. Hostikka, Howard R. Baum
An overview of a methodology for simulating fires and other thermally-driven, low-speed flows is presented. The model employs a number of simplifications of the governing equations that allow for relatively fast simulations of practical fire scenarios. The

Mathematical Modeling of Wildland-Urban Interface Fires.

September 14, 2011
Author(s)
Randall J. McDermott, Ronald Rehm
This paper presents a simple model to demonstrate the effect on grass-fire propagation of the winds induced by structural fires in a Wildland-Urban Interface (WUI) setting. The model combines an empirical formula for wind-driven grass-fire spread and a

A Simple Reaction Time Scale for Under-Resolved Fire Dynamics

June 20, 2011
Author(s)
Randall J. McDermott, Kevin B. McGrattan, Jason E. Floyd
A reaction time scale model is developed for use in the eddy dissipation concept (fast chemistry limit) closure of the mean chemical source term in large-eddy simulation of fires. The novel aspect of the model is to consider a scaling regime for coarse

CFD Simulations on Extinction of Co-Flow Diffusion Flames

June 19, 2011
Author(s)
Randall J. McDermott, Jukka Vaari, Jason E. Floyd
An improved flame extinguishing criterion is implemented to the Fire Dynamics Simulator (FDS) for gaseous suppressants under the lumped species model with transport-limited combustion (infinitely fast chemistry). The criterion considers the total enthalpy

This paper presents a simple model to demonstrate the effect on grass-fire propagation of the winds induced by structural fires in a Wildland-Urban Interface (WUI) setting. The model combines an empirical formula for wind-driven grass-fire spread and a

MODELING THE BURNING OF COMPLICATED OBJECTS USING LAGRANGIAN PARTICLES

July 4, 2010
Author(s)
Kevin B. McGrattan, Randall J. McDermott, William E. Mell, Glenn P. Forney, Jason E. Floyd, Simo A. Hostikka
A methodology is described for representing complicated objects within a computational fluid dynamics model. These objects are typically collections of similar items that are too small to define on the numerical grid that is used to solve the governing
