摘 要:
同沟敷设管道中成品油管道和原油管道间的传热对原油管道的运行有一定的影响。采用非结构化有限容积法,对成品油和原油管道内复杂的流动和传热问题进行了数值模拟。为了确定同沟敷设成品油管道对原油管道的影响,对相同条件下单独敷设的原油管道进行了水力和热力计算,并与同沟敷设管道的计算结果进行了对比。结果表明,两条管道的间距取1.2m时,原油管道沿线温度受成品油管道的影响较小。[著者文摘]

Abstract:
The heat transmission of products pipeline along with hot crude pipeline in one ditch has some effects on the operation of crude oil pipeline. The unstructured-finite-volume method was used to investigate the complex flow and heat transfer state in the products pipeline and hot crude pipeline laying in one ditch by numerical simulation. The hydraulic and thermal calculations of single crude pipeline and two pipelines for products and crude oil under the same condition were carried out. The result shows that the temperature of crude oil in the pipeline is almost unaffected by the products pipeline, when the interval between two pipelines was 1.2 meters.[著者文摘]
