##### By: Kuo-Long Pan and Roman Fursenko

Description: We have studied the outward propagation of a cylindrical flame by means of a flame-tracking numerical method and direct computation of the Sivashinsky equation. The flame speed is modified by the local curvature, via a Markstein length ℓ, that somehow groups the complicated physiochemical effects and can be monotonically relevant to the system pressure. The flame is found to accelerate in a universal profile as a function of time, which is insensitive to ini...
