Experimental Study on Impact of Ignition Energy on Gas Explosion Dissemination Pressure
Abstract：The paper studies the pressure of gas explosion under ignition energy.The research of gas explosion dissemination in pipeline under different ignition energy.Based on analysis,the result of experiment indicates that the peak pressure of explosion decreases at first,appearing to turn a point after spreading a distance,Finally,the pressure rose to reach in the maximum value near the exit;The greater the ignition energy,the greater the peak pressure of gas explosion;The peak pressure of gas explosion presented quadratic function with the aspect ratio when on the condition of a certain ignition energy;The peak pressure of gas explosion presented quadratic function with the ignition energy when on the condition of a certain aspect ratio;The peak pressure of gas explore appeared in exit at first,while the latest exposure time was near the source;The greater ignition energy,the sooner exposure time of explosion pressure.
