Analytical study in the mechanism of flame movement in horizontal tubes ...

WebThe flame acts as a volume/energy source that leads to discontinuities in flow properties or their derivatives, such as velocity, vorticity, or entropy. Wrinkling on the flame also leads to modification of the approach flow velocity field. ... A unified model of flames as gasdynamic discontinuities Journal of Fluid Mechanics 2003 491 11CrossRef ... WebFlame stretch. In combustion, flame stretch ( ) is a quantity which measures the amount of stretch of the flame surface due to curvature and due to the outer velocity field strain. The concept of flame stretch was introduced by Karlovitz in 1953. [1] [2] [3] George H. Markstein studied flame stretch by treating the flame surface as a ... novel with character heathcliff

WebAug 27, 2003 · Viewed on a hydrodynamic scale, flames in experiments are often thin so that they may be described as gasdynamic discontinuities separating the dense cold … WebViewed on a hydrodynamic scale, flames in experiments are often thin so that they may be described as gasdynamic discontinuities separating the dense cold fresh mixture from the light hot burned products. The original model of a flame as a gasdynamic discontinuity was due to Darrieus and to Landau. WebFeb 16, 2012 · As will be discussed in Sec. IV A, steady flame propagation in tubes bears some 2D traits, so it is worth mentioning here that the critical Reynolds number for the 2D Poiseuille flow is ≈5800. Google Scholar; 27. M.
