Interaction of the flames of diluted methane-oxygen mixtures with obstacles of conical shape

Abstract

It is experimentally shown that the flame of methane-oxygen mix does not get through the central opening of a confuser up to the opening angle of 83 0 , but gets through the central opening of the diffuser, despite of the existence of additional openings on cone elements. The results of numerical modeling with the use of the equations of Navier-Stokes in the compressible reacting environment in acoustic approach allowed to describe qualitative features of flame propagation through an obstacle of conical shape with additional openings on cone elements.
