Influence of Various Parameters on Initiation, Stability, and Limits of Detonations.

Abstract

The propagation of spherical flames has been investigated under conditions where artificial turbulence was generated by spherical grids at a certain distance from the center. The flame propagation velocity increases when the flame passes the net. The increase of flame velocity depends on laminar flame speed, mesh size of the grid and diameter of the wire of the grid. There exists a lower limit of the Reynolds-number below which no flame acceleration occurs.
