Experimental Study on Character about Shock Wave of Gas Explosion via Pipeline Corner

摘要

Though the gas explosion accident is serious and complex, gas explosion in coal mine has long plagued the safety of production. Accordingly, the propagation law research on shock wave of gas explosions is significant for preventing and controlling the damage of shock wave. The spread law of gas explosive shock wave via pipeline corner is researched. In general air districts, propagation rule formula of gas explosion shock wave via the pipeline corner is obtained. The relation between propagation rule of shock wave and initial pressure and pipeline corner angle is discovered under circs of shock wave passing though pipeline corner. A kind of new method for the research of the gas explosive spread rules in the future is offered.
