| 摘 要： | 在顺序输送成品油时,后行油品的输量有时会因故突然发生变化,从而导致混油特性的改变。针对此问题,以多相流模型为依据,建立了顺序输送混油控制方程,采用有限体积法进行了离散性数值计算。研究结果表明,混油特性随后行油输量的变化而变化,而且在不同时间段内的变化规律不同;后行油输量变大有助于减小混油量;当输送顺序不同时,后行油输量的变化对混油量增长速度的影响也不同。

| Abstract: | The transportation quantity of backward products in batch transportation of products often changed for some reasons, resulting in the changes of feature of mixed oil during batch transportation. To solve this problem, the governing equations of contaminated product were established based on multiphase flow model. Discrete numerical calculation were made with finite-volume method. The results show that the law of mixed-oil＇ s feature variation is different with the quantity of backward products and among different periods. The increase of the transportation quantity of backward products can reduce the mixed volume, and when transportation sequence is different, the influence of changes of transportation quantity on growth rate of the mixed volume is also different. |
