WebOct 1, 2024 · The Darrius-Landau instability has an impact on flame deformation, which was strengthened with growing initial pressure, while the thermo-diffusive instability could be neglected during combustion. At later stages after tulip inversion, the flame-acoustic wave interaction was relatively outstanding inducing wrinkled flame front and cellular ...

Fluctuation-induced diffusive instabilities Nature
Diffusive–thermal instability or thermo–diffusive instability is an instrinsic flame instability that occurs both in premixed flames and in diffusion flames and arises because of the difference in the diffusion coefficient values for the fuel and heat transport, characterized by non-unity values of Lewis numbers. The instability mechanism that arises here is the same as in Turing instability explaining chemical morphogenesis, although the mechanism was first discovered in the contex… WebA dissipative system is a thermodynamically open system which is operating out of, and often far from, thermodynamic equilibrium in an environment with which it exchanges … breasts post pregnancy

Webseminal paper,4 Turing predicted two types of diffusive in-stabilities in homogeneous media, one of which ~now gener-ally known as the Turing instability! generates … WebJan 1, 2024 · This work considers a two-dimensional hyperbolic reaction-diffusion system with different inertia and explores criteria for various instabilities, like a wave, Turing, and Hopf, both theoretically and numerically. It is proven that wave instability may occur in a two-species hyperbolic reaction-diffusion system with identical inertia if the diffusion … WebIn this paper an epidemic model is proposed to describe the dynamics of disease spread among patches due to population migration.
