NIST 14. NIST Mixture Property Database

October 16, 2008
Author(s)
Daniel G. Friend
The NIST Mixture Property Database calculates thermodynamic and transport properties of mixtures of fluids selected from any of 17 possible pure components. The emphasis of the database is on density prediction (especially for CO2-rich mixtures), but for

Physical and Chemical Data, Section 2

November 13, 2007
Author(s)
Daniel G. Friend, Bruce E. Poling, George H. Thomson, Thomas E. Daubert, Evan Buck
This Section provides tabular material for the physical and chemical properties of substances of interest to the chemical engineering community. Many of the tables have been generated using NIST standard reference data formulations, which provide

The third industrial fluid properties simulation challenge

September 7, 2007
Author(s)
F Case, John K. Brennan, Anne M. Chaka, Kerwin Dobbs, Daniel G. Friend, David Frurip, Peter A. Gordon, J Moore, Raymond D. Mountain, J Olson, Richard B. Ross, Martin Schiller, Vincent K. Shen
The third Industrial fluid properties simulation challenge was held from March to September 2006. As in the previous two events, contestants were challenged to predict specific, industrially relevant, properties of fluid systems. Their efforts were judged

Benchmarks for the Third Industrial Fluids Simulation Properties Challenge

June 28, 2007
Author(s)
Peter A. Gordon, Martin Schiller, Chien-Ping Chai Kao, Scott Bair, Daniel G. Friend
We outline the procedures used to establish benchmark physical property data for the Third Industrial Fluids Simulation Challenge. For both challenge problems, this involved measurement of new data. When possible, measurements were compared with published

Development of an Experimental Database and Kinetic Models for Surrogate Diesel Fuels

April 16, 2007
Author(s)
J T. Ferrell, N Cernansky, F L. Dryer, Daniel G. Friend, C A. Hergart, C K. Law, R M. McDavid, Christian Mueller, A K. Patel, Heinz Pitsch
Computational fluid dynamic (CFD) simulations that include realistic combustion/emissions chemistry hold the promise of significantly shortening the development time for advanced, high efficiency, low emission engines. However, significant challenges must

Development of an Experimental Database and Kinetic Models for Surrogate Jet Fuels

March 1, 2007
Author(s)
M Colket, T Edwards, S Williams, N Cernansky, D L. Miller, Fokion N. Egolfopoulos, P Linstedt, Ram Seshadri, F L. Dryer, C K. Law, Daniel G. Friend, David Lenhert, Heinz Pitsch, A Sarofim, M Smooke, Wing Tsang
The engineering and scientific community ha been searching for the identification of surrogate fuels that can reasonably represent the performance and emissions behavior of jet fuels (e.g. Jet A and JP-8) in engines. Many proposals exist in the literature

Thermophysical Properties Measurements and Models for Rocket Propellant RP-1: Phase I

February 1, 2007
Author(s)
Joe W. Magee, Thomas J. Bruno, Daniel G. Friend, Marcia L. Huber, Arno D. Laesecke, Eric Lemmon, Mark O. McLinden, Richard A. Perkins, J?rg Baranski, Jason A. Widegren
Accurate knowledge of thermophysical properties is a prerequisite to design efficient and cost-effective rocket engine systems that use the kerosene rocket propellant designated RP-1. A robust properties model that is based on reliable experimental

Correlation for the Vapor Pressure of Mercury

September 12, 2006
Author(s)
Marcia L. Huber, Arno D. Laesecke, Daniel G. Friend
We present a new correlation for the vapor pressure of mercury that is valid from the triple point to the critical point. The equation is a Wagner-type form, where the terms of the equation are selected using a simulated annealing optimization algorithm

Supplementary Backward Equations for Pressure as a Function of Enthalpy and Entropy p(h,s) to the Industrial Formulation IAPWS-IF97 for Water and Steam

July 11, 2006
Author(s)
H J. Kretzschmar, J Cooper, A Dittmann, J Trubenbach, Th Willkommen, Daniel G. Friend, J S. Gallagher, Radim Mares, Kiyoshi Miyagawa, Wolfgang Wagner, K Knobloch, I. Stocker
In 2001, the International Association for the Properties of Water and Steam (IAPWS) adopted backward equations for pressure as a function of enthalpy and entropy p(h, s) as supplement to the IAPWS Industrial Formulation 1997 for the Termodynamic

Standardized Equation for Hydrogen Gas Densities for Fuel Consumption Applications

April 3, 2006
Author(s)
Eric Lemmon, Marcia L. Huber, Daniel G. Friend, Carl Paulina
One of three currently recognized methods for evaluating the consumption of gaseous hydrogen fuel in vehicle applications involves the determination of the equilibrium temperature and pressure of the gas before and after usage within a storage tank of

The Vapor Pressure of Mercury

April 1, 2006
Author(s)
Marcia L. Huber, Arno D. Laesecke, Daniel G. Friend
In this report, we review the available measurements of the vapor pressure of mercury and develop a new correlation for the vapor pressure of mercury that is valid from the triple point to the critical point. The equation is a Wagner-type form where the
