Dynamic course from combustion to explosion of gas in half closed space
Abstract：The dynamic course of flame spread of gas explosion in half closed space in initial stage was studied by experimentation,based on the relationship of the rate of flame front with the rate of chemical reaction of gas explosion.The reaction rate constant of gas explosion in initial stage is directly proportional to square of the rate of flame spread;the rate of chemical reaction is the main influence factor of the dynamic course from combustion to explosion of gas.The position and rate of flame front increase exponentially with time in initial stage of gas explosion.The gas reaches the explosion stage when the rate of flame reaching the en times of the initial rate of gas beginning combustion.The induction period of gas explosion includes the induction period of gas combustion and the response time from combustion to explosion.The induction period of gas combustion is from gas beginning to react to flame appearing.The response time from combustion to explosion is n times of t.
