油气管道敷设中存在两种并行敷设方式,输油管道并行敷设和油气管道并行敷设。受焦耳汤姆逊效应和管径差别等因素的影响,油气管道并行敷设与两条输油管道并行敷设热力影响情况有所不同。本文采用有限差分法和有限容积法相结合的数值计算方法研究了这两种不同并行敷设热力影响的区别。
There are two parallel laying ways for oil and gas pipeline laying. Oil pipeline laying in parallel and oil and gas pipeline laying in parallel. Affected by factors such as Joule Thomson effect and differences in pipe diameter, the thermal impact of parallel laying of oil and gas pipelines and parallel laying of two oil pipelines is different. In this paper, finite difference method and finite volume method are used to study the difference between the two different parallel thermal effects.
