Oleophilic skimming is a primary alternative when addressing oil spill accidents. However, the existing literature does not define accurately the optimum design and operating conditions of the oleophilic skimmer. In this research, an extensive CFD investigation was conducted on the performance of the drum skimmer. Seven parameters were tested, namely drum diameter, drum centre height, oil slick thickness, rotational speed, oil density, oil viscosity and oil surface tension. The simulations were performed by applying the volume of fluid technique using the OpenFOAM package. The two-dimensional numerical setup was tested for grid size, domain extension and time-step convergence, and the results were validated with experimental data from the literature. The skimmer performance was evaluated through the oil recovery rate and water ingestion rate. The study illustrated that the oleophilic drum skimmer best functions at rotational speed within 30–60 rpm, drum diameter within 200–300 mm, drum centre-height-to-diameter ratio within 0.3–0.4, oil slick thickness \(\ge\) 15 mm and oil viscosity within 10–100 cSt.

亲油撇油过程的参数研究:使用 VOF 模型的 CFD 模拟

亲油撇油是处理溢油事故的主要替代方法。然而,现有文献并未准确定义亲油分离器的最佳设计和操作条件。在这项研究中,对鼓式收油机的性能进行了广泛的 CFD 调查。测试了七个参数,即滚筒直径、滚筒中心高度、浮油厚度、转速、油密度、油粘度和油表面张力。模拟是通过使用 OpenFOAM 包应用流体体积技术进行的。对二维数值设置进行了网格大小、域扩展和时间步长收敛的测试,并使用文献中的实验数据验证了结果。撇油器性能通过采油率和吸水率进行评价。\(\ge\) 15 mm 和油粘度在 10–100 cSt 范围内。
