Abstract

Abstract

Natural gas is an important energy material for national development, but its hazardous properties lead to frequent explosion accidents. In order to pre-evaluate the maximum overpressure of natural gas explosion under the condition with external turbulence, it is proposed to reveal the mechanism of accelerated propagation of turbulent flame, and to establish a prediction model of natural gas explosion overpressure coupled with external turbulence. To this end, an experimental platform for natural gas explosion under external turbulence was firstly established, and the particle image velocimetry system was used to obtain the intensity of external turbulence. Then, the effects of external turbulence with different turbulent intensities on the flame evolution, flame front velocity and explosion overpressure of natural gas explosion were obtained for the methane-air premixed gas with stoichiometric ratio. Finally, through introducing the folding factors of flame instability-induced folds, flame turbulence-induced folds and external turbulence-induced folds, a theoretical model of predicting maximum explosion overpressure of natural gas explosion by considering external turbulence is established. The results indicated that compared with the condition without external turbulence, the external turbulence can exacerbate the degree of flame surface folds. Without external turbulence, the flame radius increases linearly with time; in the presence of external turbulence, the flame is characterized by self-accelerating propagation. The flame acceleration can be triggered by external turbulence, with the increasing intensity of external turbulence, the flame front velocity increases gradually. Additionally, with the increasing intensity of external turbulence, maximum explosion overpressure and maximum rate of pressure rise continue to increase. With the increasing distance between pressure monitoring point and ignition position, maximum explosion overpressure and maximum rate of pressure rise totally decrease. The flame acceleration must be considered to predict natural gas explosion overpressure under external turbulence. Maximum explosion overpressure measured in the experiments is between the value calculated using laminar flame model and turbulent flame model.
