William J. Boettinger, Dilip K. Banerjee
In this chapter, we give a general view of the formation of the solid from its melt. This process is generally driven by the extraction of heat from the melt but fluid flow has a major influence on solidification. Thus an early section deals with transport

Software Independent Data Mapping Tool for Structural Fire Analysis

March 12, 2014
Dilip K. Banerjee
In order to model the structural behavior under fire, three separate analyses need to be conducted: a) fire propagation and growth (fire modeling), b) transient heat transfer in structural members due to fire, and c) structural analysis to account for both

Practical CFD Simulations of Wind Tunnel Tests

December 1, 2013
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

Uncertainties in Steel Temperatures during Fire

August 4, 2013
Dilip K. Banerjee
In order to determine the fire resistance of steel members, steel temperatures must be estimated with a high confidence. There can be considerable uncertainty in temperatures of both protected and unprotected steels during fire exposure. This is due to

Dong Hun Yeo, Franklin T. Lombardo, Dilip K. Banerjee, Eric J. Letvin, Emil Simiu, Marc L. Levitan, Florian A. Potra
The paper summarizes recent research and development of computer-aided and computational methods in wind engineering at the National Institute of Standards and Technology (NIST). Specific topics to be covered include: 1. Time-domain database-assisted

An Integrated Interactive Visualization and Analysis Environment to study the Impact of Fire on Building Structures

July 25, 2010
Dilip K. Banerjee, John L. Gross, Pradeep R. Gaddam, Thomas M. Olano, William J. Hess, Judith E. Terrill, Terence J. Griffin, John G. Hagedorn, John T. Kelso, Steven G. Satterfield
We have created an integrated interactive visualization and analysis environment, that can be used immersively or on the desktop, to study the interaction among fire, heat transfer, and structural deformation computed from three linked simulations. In this

Visualization of Structural Behavior under Fire

August 12, 2009
Dilip K. Banerjee, William J. Hess, Thomas M. Olano, Judith E. Terrill, John L. Gross
An integrated environment was created to study the interaction among fire, heat transfer, and structural deformation from a typical room fire. The fire, thermal, and structural data were linked with a separate 3-D visualization capability, to provide the

Calculation of Relative Thermal Elongation of Structural Steels

May 2, 2009
Dilip K. Banerjee, Ursula R. Kattner
In the recent past, there has been a number of studies toward predicting the thermal and structural behavior of components subjected to elevated temperature due to an exposure to fire. Numerical modeling has been applied quite extensively toward this end
