The governing equations are discretized using the fi nite volume method. The variations in temperatures of static oil and soil were investigated during pipeline shutdown in both summer and winter,in which some important parameters of the soil and crude oils of a Northeast pipeline are employed. 关键词：原油管道建设数值模拟非结构化网格关机土壤温度有限体积法数学模型区域电网
