Double Method of Characteristics to Analyze Hydraulic-Thermal Transients of Pipeline Flow

Department of Petroleum Supply Engineering, Chongqing College of Logistic Engineering, Chongqing 400016, P R China

摘要: 研究了管道内流体流动的水力瞬变及热力瞬变,改进了分析介质顺序输送管流水力瞬变的特征线法;推导了含流速v的 3次方的热力瞬变方程,构造了相应的特征线法;建立了分析介质顺序输送管流耦合的水力-热力瞬变的双特征线法。

Abstract: The hydraulic and thermal transients in pipeline flow were studied.The method of characteristics for hydraulic transient analysis of batch transport of pipeline flow had been improved.The thermal transient equation,in which the term with v³ was involved,had been inferred,while the corresponding method of characteristics was constructed.The double method of characteristics,which can be used to study the coherent hydraulic-thermal transients of batch transport of pipeline flow,was developed.
