Wick-Type Liquid-Metal Combustion MAY 91 85 pages
Authors:  L.-d. Chen; H. Y. Lyu; K. Y. Hsu; IOWA UNIV IOWA CITY DEPT OF MECHANICAL ENGINEERING
The full text of this report is available for sale.An investigation was conducted to study wick combustion of Li and SF6. A single-line laser induced fluorescence thermometry with Li2 as fluorescence species was developed. Wick combustion of Li and SF6 was conducted in vacuum chamber at sub-atmospheric pressures. The combustion results in a bright pinkish flame. Emission spectra shoe that the flame luminosity is dominated by the resonance-emission line of Li atoms. On analysis, a conserved scalar approach was ...


Wick-Type Liquid-Metal Combustion OCT 89 68 pages
Authors:  L. D. Chen; H. Y. Lyu; K. Y. Hsu; IOWA UNIV IOWA CITY DEPT OF MECHANICAL ENGINEERING
The full text of this report is available for sale.An experimental and theoretical investigation was conducted to study the wick combustion of Lithium and Sulfur hexafluoride. A single-line laser induced fluorescence thermometry with Li2 as fluorescence species was developed. The calibration experiments yielded promising results; refinements, however, are needed before the technique can be applied to combustion flame measurements. Wick combustion of ethanol and hexane in air as well as Li and SF6 was conducted in a vacuum chamber ...
