Thermal Conductivities of Alternatives to CFC-11 for Foam Insulation

April 1, 2001
Author(s)
Richard A. Perkins, L -. Cusco, J -. Howley, Arno R. Laesecke, S -. Matthes, M L. Ramires
The present work examines the thermal conductivities of several dilute vapors which are potential alternatives to chlorofluorocarbons (CFCs) for cellular-plastic foams. Thermal conductivity data are reported in the vapor phase, from 280 to 340 K, for

M L. Ramires, Carlos A. Nieto de Castro, Richard A. Perkins
New experimental data on the thermal conductivity of propane have been reported since the wide-range correlations proposed by Holland et al. And by Younglove and Ely. These new experimental data, covering a temperature range of 110 to 700 K and a pressure

Reference Data for the Thermal Conductivity of Saturated Liquid Toluene Over a Wide Range of Temperatures

October 1, 1999
Author(s)
M L. Ramires, Carlos A. Nieto de Castro, Richard A. Perkins, Y Nagasaka, A Nagashima, Marc J. Assael, William A. Wakeham
Efficient design of industrial processes and equipment requires accurate thermal conductivity data for a variety of fluids, such as alternative refrigerants, fuels, petrochemicals, aqueous systems, molten salts, and molten metals. The accuracy of
