Density measurements of compressed-liquid dimethyl ether + pentane mixtures

January 1, 2016

Stephanie L. Outcalt, Eric W. Lemmon
Compressed-liquid densities of three compositions of the binary mixture dimethyl ether (CAS No. 115-10-6) + pentane (CAS No. 109-66-0) have been measured with a vibrating U-tube densimeter. Measurements were made at temperatures from 270 K to 390 K with

Compressed-liquid density measurements of three alternative turbine fuels

Heavier kerosene based liquid fuels for aircraft and rockets are required to meet stringent performance specifications. Nevertheless, the escalating cost, unpredictable supply, and environmental impacts of traditional petroleum based fuels used for that

Compressed-liquid Density Measurements of Three Alternative Turbine Fuels

February 7, 2014

Stephanie L. Outcalt
Compressed-liquid densities of three alternative turbine fuels have been measured. The measurements were made from 270 K to 470 K, and 0.5 MPa to 50 MPa. The data have been correlated with a Tait equation, and parameters are given for each fuel. Results of

Advanced Calibration, Adjustment, and Operation of a Density and Sound Speed Analyzer

Benchtop measurement systems have emerged as powerful tools in the ongoing quest for thermophysical property data. We demonstrate that these instruments can yield high quality data if operated in an informed manner. The importance of sample purity

Density and Speed of Sound Measurements of Four Bio-derived Fuels

September 13, 2012
Author(s)
Stephanie L. Outcalt, Tara J. Fortin
Compressed-liquid densities and ambient pressure densities and speeds of sound of four biomass-derived fuels have been measured. The compressed-liquid measurements were made from 270 K to 470 K, and 0.5 MPa to 50 MPa. The ambient pressure measurements were

Compressed-liquid densities of two highly polar + non-polar binary systems

Stephanie L. Outcalt, Arno R. Laesecke
The binary systems ethanol + 2,2,4-trimethylpentane and 2-butanol + 2,2,4-trimethylpentane were studied as models for blends of gasoline with biofuels. Their densities were measured with a vibrating-tube densimeter at compressed-liquid states of three

Compressed-Liquid Density Measurements of Methyl Oleate and Methyl Linoleate

September 30, 2011
Author(s)
Stephanie L. Outcalt
Compressed liquid densities of the fatty acid methyl esters methyl linoleate and methyl oleate have been measured with a vibrating-tube densimeter. The temperature and pressure range of the measured data is from 270 K to 470 K, and 0.5 MPa to 50 MPa. The

Density and Speed of Sound Measurements of Two Synthetic Aviation Turbine

June 29, 2011

Stephanie L. Outcalt, Tara J. Fortin
Rising prices and the uncertain supply of petroleum based aviation fuels have led to an interest in substitute fuels made from non-petroleum sources. Synthetic isoparaffinic kerosenes (S-IPK) are among the most promising alternatives. Two instruments were
