摘要:
为研究油流携水过程中的积水运动特性，明确排除积水临界条件。以0#柴油、自来水为实验介质，利用内径（D）为50，80 mm，上倾倾角（β）为1°，5°，10°的水平-上倾实验环道，对表观油速（Uos）为0.25 m/s、无量纲水相高度（h/D）在0.5范围内，油流剪切作用下的管道积水运动特征进行实验。研究结果表明：积水流型随表观油速、无量纲水相高度、上倾倾角的增大由光滑分层流逐渐向波状分层流、液滴分层流过渡，其中表观油速影响最为显著；积水爬坡距离随表观油速增加而显著增加，随上倾倾角增大而减小，随无量纲水相高度减小而减小；实验说明弗劳德相似准则能较为准确地预测起伏管道中积水携带临界表观油速；由弗劳德相似准则预测可知，内径为489 mm管道积水排除的临界表观油速约为1.60 m/s，研究结果对减少管道内腐蚀有一定指导意义。
Abstract:
In order to study the movement characteristics of accumulated water in the process of oil flow carrying water,and clarify the critical conditions for eliminating accumulated water,taking 0# diesel oil and tap water as test media,the movement characteristics of accumulated water in the pipeline under the effect of oil flow shear with the apparent oil velocity (Uos) of 0.25 m/s and the dimensionless water phase height (h/D) within 0.5 were studied experimentally by using the horizontal and upward inclined test loop with the inner diameter of 50,80 mm and upward inclined angle of 1°,5° and 10°.The results showed that the flow pattern of accumulated water transited gradually from smooth stratified flow to wavy stratified flow and droplet stratified flow as the apparent oil velocity,dimensionless water phase height and upward inclined angle increased,and the influence of apparent oil velocity was the most significant.The grade climbing distance of accumulated water increased dramatically with the increase of apparent oil velocity,while decreased with the increase of upward inclined angle and the decrease of dimensionless water phase height.The experimental results showed that Froude similarity criterion could be used to predict the critical apparent oil velocity of carrying accumulated water in undulating pipelines more accurately.According to the prediction of Froude similarity criterion,the critical apparent oil velocity of accumulated water exclusion in the pipeline with inner diameter of 489 mm was about 1.60 m/s.The research results have certain guiding significance for reducing the internal corrosion of pipelines.
