Investigation on the characteristics of single-phase gas explosion and gas-coal dust coupling explosion in bifurcated tubes

In order to deeply understand the overpressure propagation characteristics of explosion shock wave single-phase gas and gas-coal dust coupling in bifurcated tube, this paper makes a comprehensive in-depth study on change distribution law tube by means experimental research, results show that: is all affected bifurcation angle larger is, greater is. terms distribution, similar overall development trend, maximum obtained front point. The mutation coefficients before after point are tube. straight section, coefficient increases gradually with increase while situation inclined section just opposite. Under condition same angle, smaller than that explosion.
