【摘要】 采用商业软件Fluent程序对油水和油砂的重力沉降分离进行了数值模拟,得到了与实验结果吻合较好的多种黏度、不同液滴和砂粒粒径情况下的重力沉降分离结果, 尤其是介质中包含多种粒径分布液滴的沉降分离结果。这对于确定油水和油砂重力沉降分离所需的时间和确定分离器容器的尺寸有很好的指导作用。更多还原

【Abstract】 The separation of oil-water and oil-sand gravity settlement was simulated numerically by the commercial software Fluent in this paper. The settlement results of different oil droplets and sand particles sizes especial some oil droplet size distributions with several viscosities were obtained,which agreed well with the experimental data.It is significant to judge the settling velocity and decide the proper projected dimension for separator.更多还原
