Research on the Real-Time Calculation of Gas Leakage and Diffusion and Hazards Prediction of Fire and Explosion for Nature Gas Pipeline

It is meaningful to research the methods for real-time gas diffusion calculation and hazardous regions predication. Considering the effect of wind, using the revised Gaussian plume model, diffusion concentration distribution of gas was calculated fast and the comparison result showed that the accuracy of the revised Gaussian plume model was significantly better than that of the Gaussian model. Moreover, the hazardous effect of fire and explosion was analyzed. A fire and explosion hazards analysis system was developed. Using this system, the hazardous areas could be predicted, safe guarantee for rescue could be achieved and the hazards of fire and explosion could be reduced. At last, using an explosion case, the effectiveness of the evaluation models was checked in the aspect of shock wave hazard and thermal radiation hazard. The checking result showed that evaluation models for diffusion calculation and hazards predication were effective.
