摘要
Abstract
By comparing results with standard calcula-tion examples,this study analyzes the influence of three key factors,i.e.pipeline internal pressure,pipe-line internal diameter and wind speed,on the conse-quences of full-diameter fracture leakage accidents in gas pipelines.The analyzed consequences include cloud diffusion height,maximum downwind distance,as well as influence range radius of jet fire accidents and explosion accidents.As the pipeline internal pres-sure and pipeline internal diameter increase,the cloud diffusion height and maximum downwind distance both increase,and the influence range radius of both jet fire accidents and explosion accidents gradually expands.As wind speed increases,the cloud diffusion height gradually decreases,while the maximum downwind dis-tance gradually increases.Furthermore,the influence range radius of both jet fire accidents and explosion ac-cidents gradually expands.However,when the wind speed exceeds 5 m/s,the change in the influence range radius of explosion accidents becomes negligible.The findings indicate that pipeline internal pressure,inter-nal diameter,and wind speed should all be considered when assessing the consequences of full-diameter frac-ture leakage accidents in gas pipelines.关键词
