Modeling the Influence of Limestone Filler on Cement Hydration in CEMHYD3D

February 1, 2006
Author(s)
Dale P. Bentz
The ASTM C150 standard specification for portland cement now permits the addition of up to 5 % limestone filler. While these and much higher levels of limestone filler substitution have been employed in Europe and elsewhere for many years, the change in

FIRE SUPPRESSANT DISTRIBUTION IN AN ENGINE NACELLE

January 1, 2006
Author(s)
David R. Keyser, J C. Hewson
The flow inside an engine nacelle ground test simulator is studied for the purpose of understanding and optimizing the distribution of suppressant. One objective of this study is to identify conditions for which suppression will and will not be successful

NGP RESEARCH ON FIRE SUPPRESSION CHEMISTRY

January 1, 2006
Author(s)
Gregory T. Linteris
Several NGP projects studied the mechanisms of chemical suppressants, including those containing halogens, phosphorus, and metals. From the work, several general principles of chemical flame inhibition are outlined. The present paper describes the
