- 摘要:
- 针对现有喷射火危害区域计算模型在预测喷射火危害区域存在计算精度不高和未充分考虑横向风影响的问题,在综合分析对比已有数学模型(单点源模型、多点源模型、固体火焰模型)的基础上,提出了精度更高且更符合实际喷射火危害区域的线性积分模型，并基于2010年美国加利福尼亚州天然气输送管道失效喷射火事故报告中的数据,进行模型可靠性验证。根据所建立的模型分析了单因素(泄漏孔孔径、横向风)作用下对危害区域的影响。研究结果表明：在考虑横向风影响时,喷射火的危害区域更接近于一个椭圆；在事故报告工况下风速为13 m/s时椭圆度最大;喷射火对下风侧的危害范围大于上风侧。研究成果可为天然气管道的建设、运行、维护提供理论基础和技术支持。
Aiming at the problems that the existing jet fire hazard consequence area calculation model has low calculation accuracy in predicting jet fire hazard and does not fully consider the impact of transverse wind, a comprehensive analysis and comparison of existing mathematical models (single point source model, multi-point source model, solid flame model), a linear integral model with higher accuracy and more in line with the shape of the actual jet fire hazard consequence area is proposed. And based on the data in the report on 2010 California natural gas pipeline failure jet fire incident, the validity of the model was verified. Finally, according to the established model, the influence of single factor (diameter of leakage hole, transverse wind) on the hazard consequence area is analyzed. The results show that the consequence area of jet fire is closer to an ellipse when the influence of transverse wind is taken into account. The ovality is the largest when the wind speed is 13 m/s under the reported working condition; the damage range of jet fire on the downwind side is greater than that on the upwind side. The research results will provide theoretical basis and technical support for the design, construction, operation and maintenance of natural gas pipelines.
