Biogas flame propagation in the interconnected pipe: The effect of biogas/air mixture concentration

Flame propagation in the interconnected pipe with various size has a potential to initiate an explosion hazard. Thus in this study, the biogas/air flame propagation was investigated in the interconnected pipe. The experiment was conducted in pipe interconnected with three different diameters which a...
