...Amit Kumar; Kevin Tolejko; James S. T'ien A detailed, two-dimensional, laminar, flame spread model over a thin solid is solved in both a normal gravity downward spread configuration and in a microgravity quiescent atmosphere configuration. The radiation transfer equation is solved using discrete...

...L. L. Dong; C. W. Leung; C. S. Cheung Experiments were carried out to study the heat transfer characteristics of a pair of premixed, laminar, rectangular, butane/air flame jets impinging vertically upon a water-cooled flat plate. The effects of jet-to-jet spacing and the nozzle-to-plate distance...

.... The fully coupled nature of the calculations without external specification of flame location represents a key advance over past efforts towards modeling of porous radiant burners, because for a given mass flow rate the actual heat loss from the flame determines its position and is not a free parameter...

...John Baker; Mark E. Calvert; David W. Murphy Results of an experimental investigation into the behavior of laminar jet diffusion flames, produced using micro-slot burner ports, are presented. Under certain conditions, the cross-sectional shape of micro-slot flames is qualitatively similar...

...S. S. Krishnan; K.-C. Lin; G. M. Faeth, Professor, Fellow ASME, Extinction and scattering properties at wavelengths of 250–5200 nm were studied for soot emitted from buoyant turbulent diffusion flames in the long residence time regime where soot properties are independent of position...

...W. H. Chen The flame structure and stability, as well as the vaporization rates of twin droplets exposed to a high-temperature, partially premixed flow are investigated in the present study. Two important parameters of the Reynolds number and ambient equivalence ratio are taken into consideration...

...S. S. Krishnan; K.-C. Lin; G. M. Faeth Nonintrusive measurements of the optical properties of soot at visible wavelengths (351.2–800.0 nm) were completed for soot in the overfire region of large (2–7 kW) buoyant turbulent diffusion flames burning in still air at standard temperature and pressure...

... method for determining flammability, ASTM E 681 has difficulty discerning the flammability boundary for weak fuels such as CH 2 F 2 . This article describes an alternative approach to identify the limits of flammability, using a twin, premixed counterflow flame. By using the extinction of an already...

...S. Bhattacharjee; M. King; W. Cobb; R. A. Altenkirch; K. Wakai Approximate methods for the determination of a temperature field using pure emission pyrometry applied to a two-dimensional nonoptically thin flame without variation along a line of sight are presented. In the absence of an absorption...

...A. Ito; A. Narumi; T. Konishi; G. Tashtoush; K. Saito; C. J.
