Flow of Alternative Agents in Piping

January 1, 1994
Author(s)
Thomas G. Cleary, William L. Grosshandler, Jiann C. Yang
As part of the USAF, Army, Navy and FAA sponsored halon replacement project, the pipe flow characteristics of selected alternative agents for engine nacelle tire protection are being studied. Due to the remote location of the agent storage bottle, piping

Simulation of Dry Bay Discharge of Alternative Agents

January 1, 1994
Author(s)
Jiann C. Yang, Thomas G. Cleary, William L. Grosshandler
As a continuation of the USAF/Navy/Amy/FAA sponsored halon replacement project, the discharge characteristics of the three selected akernative agents (CFJ, FC-218. and HFC- 125) for dry bay applications will be further evaluated. Halon 1301 will also be

Agent Screening for Halon 1301 Aviation Replacement

October 20, 1993
Author(s)
William L. Grosshandler, Richard G. Gann, Anthony P. Hamins, Marc R. Nyden, William M. Pitts, Jiann C. Yang, Michael R. Zachariah
A comprehensive experimental program is described in which eleven gaseous agents and sodium bicarbonate powder have been screened, so that the best three candidates for subsequent full-scale aircraft fire extinguishment evaluation can be identified

Dynamics of the Release of Alternate Halon Replacement Agents From Pressurized Bottles

May 11, 1993
Author(s)
William M. Pitts, Jiann C. Yang, B D. Breuel, W G. Cleveland, G. Gmurczyk
Halon 1301 has been widely employed on military and commercial aircraft for fire fighting purposes. Unfortunately, due to the deleterious effects of chlorine and bromine on stratospheric ozone, the manufacture of halon 1301 will be phased out by the end of

Solubilities of Nitrogen and Freon-23 in Alternative Halon Replacement Agents

May 11, 1993
Author(s)
Jiann C. Yang, B D. Breuel, William L. Grosshandler
As part of the USAF-sponsored halon replacement project, solubility measurements of nitrogen and Freon-23 in eleven potential halon replacement agents and evaluations of the thermodynamic properties of the agents are currently being conducted at NIST. The

Heterogeneous Combustion

January 1, 1993
Author(s)
Jiann C. Yang
The term "heterogeneous" in this chapter is used loosely to refer to systems in which there are two phases. Under this classification, the subject of heterogeneous combustion is so broad that it is impossible to cover every aspect of it in this chapter
