Effects Of Obstacles On Premixed Hydrogen-Air Mixtures Explosion In Closed Pipe

Results of experiments on explosion premixed hydrogen-air are presented. The data covers a wide range of hydrogen concentration between 13 to 54 % v/v (Ф= 0.4 to 1.8). The experimental work was performed in a closed pipe containing 90 degree bends with a volume of 0.42 m3operating at ambient conditi...
