【摘要】：温度梯度是传热传质过程的动力来源之一,顺序输送本质上是传热与流动、传质的耦合过程.当前,对混油拖尾现象、与热力耦合的调度方法、管内三维传热传质模拟、考虑油品质量潜力的批次跟踪的相关研究中大多未考虑温度的影响也未阐明温度的作用机制.本文总结了未充分考虑温度影响的管输油品相关研究(混油、调度、热油管道、批次跟踪)的现状和局限性.评述了考虑温度对混油机理影响、温度对管输过程流动传热传质影响的国内外研究成果,并梳理了相关的实验研究.最后指出了水热力耦合的调度、考虑温度影响的反常扩散、可压缩多相紊流的三维数值模拟、复杂管道中的批次跟踪是该领域今后研究的关键问题和发展方向.
[Abstract]:Temperature gradient is one of the dynamic sources of heat and mass transfer. Sequential transport is essentially a coupled process of heat and mass transfer.At present, most of the related researches on the trailing phenomenon of mixed oil, thermo-mechanical coupling scheduling method, three-dimensional heat and mass transfer simulation in pipe, and batch tracking considering the potential of oil quality do not consider the effect of temperature or clarify the mechanism of temperature.This paper summarizes the current situation and limitations of related researches on pipeline oil products (mixed oil, dispatching, hot oil pipeline, batch tracking) which do not fully take into account the influence of temperature.This paper reviews the domestic and foreign research results considering the effect of temperature on the oil mixing mechanism and the influence of temperature on the flow heat and mass transfer in pipe transportation process.Finally, it is pointed out that the key problems and development direction in this field are the scheduling of water-thermodynamic coupling, the anomalous diffusion considering the influence of temperature, the three-dimensional numerical simulation of compressible multiphase turbulent flow and the batch tracking in complex pipelines.
