Abstract

The temperature field of a premixed butane/air slot laminar flame jet is visualized by studying the interferogram of the flame using Mach-Zehnder Interferometry. The introduction of a slot burner with a large aspect ratio enables the three-dimensional temperature field of the flame to be observed directly from the fringe patterns of the obtained two-dimensional interferogram. Subsequently, the temperature field of an open flame jet at a specified Reynolds number or equivalence ratio is studied by varying one parameter while keeping the other unchanged. At the Reynolds number of 400, temperature fields of the flame jet at different equivalence ratios ranging from 1.0 to 2.0 are studied and compared. Similarly, at an equivalence ratio of 2.0, temperature fields of the flame jet at different Reynolds numbers ranging from 400 to 900 are investigated. In the present study, a non-contact method is successfully developed to measure the temperature field of a premixed butane/air slot laminar open flame jet.
