Journal ArticleDOI
Nonlinear analysis of hydrodynamic instability in laminar flames—I. Derivation of basic equations
TL;DR: In this paper, an asymptotic nonlinear integrodifferential equation for spontaneous instability of the plane front of a laminar flame is derived, and it is shown that in all cases spontaneous instability implies an increase in its propagation velocity.
Journal ArticleDOI
Nonlinear analysis of hydrodynamic instability in laminar flames—II. Numerical experiments
D.M. Michelson,G.I. Sivashinsky +1 more
TL;DR: In this article, the formation of a wrinkled noncellular laminar flame front under conditions of spontaneous hydrodynamic instability and spontaneous diffusional-thermal instability was studied.
Journal ArticleDOI
On a distorted flame front as a hydrodynamic discontinuity
TL;DR: The propagation velocity of a distorted flame front (relative to the gas) can be determined explicitly as a function of the hydrodynamic field and the physico-chemical parameters of the gaseous mixture as mentioned in this paper.
Journal ArticleDOI
On self-turbulization of a laminar flame
TL;DR: In this paper, an asymptotic nonlinear differential equation is derived for the evolution of a disturbed spherical flame front, and a quantitative description is presented of the formation of cellular flame structure and subsequent self-turbulization of the flame.
Journal ArticleDOI
Hydrodynamic theory of flame propagation in an enclosed volume
TL;DR: In this article, a hydrodynamic description of slow flame propagation in a vessel of constant volume and the associated temperature gradient effect in the combustion products is proposed. But the model is restricted to the case when the Mach number tends to zero.
