Book Synopsis Experimental Investigation of Laminar Gas Jet Diffusion Flames in Zero Gravity by : Thomas H. Cochran
Download or read book Experimental Investigation of Laminar Gas Jet Diffusion Flames in Zero Gravity written by Thomas H. Cochran and published by . This book was released on 1971 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental program was conducted to study the burning of laminar gas jet diffusion flames in a zero-gravity environment. The tests were conducted in the Lewis Research Center's 2.2- Second-Zero-Gravity Facility and were a part of a continuing effort investigating the effects of gravity on basic combustion processes. The photographic results indicate that steady state gas jet diffusion flames existed in zero gravity but they were geometrically quite different than their normal-gravity counterparts. Methane-air flames were found to be approximately 50 percent longer and wider in zero gravity than in normal gravity.

Book Synopsis Effects of Gravity on Laminar Gas Jet Diffusion Flames by : Thomas H. Cochran
Download or read book Effects of Gravity on Laminar Gas Jet Diffusion Flames written by Thomas H. Cochran and published by . This book was released on 1970 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental program was conducted to study the burning of laminar gas jet diffusion flames in a zero-gravity environment. The tests were conducted in the Lewis Research Center 2.2-Second Zero-Gravity Facility. The photographic results indicated that a sudden decrease in gravity level from 1 to 0 effected an immediate reduction in the length of the flame. Continued time in zero gravity resulted in the flame expanding away from the burner until extinguishment appeared to occur. Nondimensionalization of the governing flow equation yielded the parameters used to correlate the buoyancy effects.

Download or read book Two-Dimensional Direct Numerical Simulation of Opposed-Jet Hydrogen/Air Flames: Transition From a Diffusion to an Edge Flame written by and published by . This book was released on 2000 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: In an opposed-jet diffusion flame experiment, under certain conditions, after the extinction of the diffusion flame, an edge flame can be obtained. It was reported recently in a numerical and an experimental work and is responsible for an interesting transition between two distinct burning flames (multiple solutions). Motivated by our previous numerical results, obtained with simplified kinetics and some recently reported experimental data, we performed direct numerical simulations of this transition to investigate the underlying physical mechanisms. The appearance of an edge flame after the extinction of the diffusion flame, the hysteresis reported in the experiments, and the existence of multiple vigorously burning flames at identical conditions are all captured by our simulations. Our numerical results show that, in the absence of an inert coflow curtain, when the diffusion flame disk is extinguished, an edge flame forms and propagates in the mixing layer. After the formation of this edge flame, even when the applied strain rate is reduced to the initial subcritical value, the diffusion flame disk does not reappear, because the local fluid velocity still exceeds the propagation speed of the edge flame. This hysteresis has significant implications in the common submodel that utilizes the strain rate as a parameter to determine local reignition in flamelet models; it indicates that a subcritical strain rate is not a sufficient condition for the reignition of a diffusion flame. Further investigation of this phenomenon is clearly needed to refine submodels of local extinction and reignition in the flamelet models for turbulent diffusion flames. The opposed-jet configuration provides a convenient platform to analyze edge flames which are stabilized aerodynamically in a two-dimensional geometry, thus making matching two-dimensional direct numerical simulations effective.
