 | We found that Electrical breakdown in a PAO fluid results in the formation of submicron carbonaceous particles and some flammable gas which, more than likely, is hydrogen. An applied electric field generates significant streaming electrification in a PAO fluid. The Navy Oil Analysis Program procedures, which were developed in the 1980s for testing unstable Coolanol fluids, fail to test the degradation of hydrolytically stable PAO fluids currently used by the ... |

| A cost effective method was proposed for the removal of heavy metal ions from small plating operations. Beltran developed a combined technique that includes 3-D (three-dimensional) electrochemical technology (ET) and electrochemical coagulation (EC), as a result of which iron hydroxide with a reproduced structure of magnetite is generated. Theoretical and experimental investigations performed in Phase I showed the feasibility of purification of wastewaters from Cr, Ni, and Cd by means ... |

| The object of this study was to explore chemical modification of extinguishants currently used against postcrash fuel-fed fires to inhibit reignition, i.e., improve 'burnback' control, without compromising the efficacy of flame knockdown. A formulation was developed as an additive to AFFF, for delivery during fire extinguishment which succeeded in 16-inch laboratory trials, but not to the same extent in 6-foot field tests. Several causes were considered and reformulation recommended. Three ... |

|
| The single most important design factor faced by the cooling systems in tactical trucks is their vulnerability to exploding shells, sniper fire, and other projectiles. This project proposes to use heat pipes in radiators to transfer waste heat from the engine to the surrounding environment. In the phase I concept feasibility study, a computer program was developed to design a small scale heat pipe radiator module. Experimental tests were performed ... |
