Abstract

In this paper the effect of meshy obstacle on methane gas explosion is experimented by high speed schlieren technique, the images of explosion flame crossing obstacle is gained and flame propagation velocity and temperature is measured. The experimental results showed that meshy obstacle disturbed unburned gas and enhanced the camber of flame front surface and the turbulent intensity of flame inner flow field, combustion reaction is more violent and fractal dimension of flame front surface and flame inner flow field increase too.
