| 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. |

| Keywords: | pipeline flow thermal transient hydraulic transient method of characteristics |
