Numerical modeling of the oil filtration process

从不同类型的油（燃料、润滑油和液压系统油）中过滤悬浮的液体/固体污染物是许多工业的重要步骤。过滤固体颗粒或液滴的最有效方法之一是使用过滤介质。由于必须考虑聚结器和分离器中存在的多孔过滤介质中流体的流动情况，因此对聚结器性能的评估是复杂的。在其他重要方面中，计算由于多孔过滤器造成的额外压降是首要目标。通常，这是通过考虑可能的几何和操作条件的多组实验来完成的。实验测试需要在设计阶段构建原型，并针对每个应用进行测试，因此成本很高；计算方法似乎是一个

Filtration of suspended liquid/solid contaminants from different type of oils (fuel, lubricant and hydraulic system oil) is an important step in many industries. One of the most effective ways of filtering solid particles or liquid droplets is the use of filter media. Assessing the performance of such filtration device is complex as it must consider the fluid flow through the porous filtration medium which exists in both coalescer and separator. Among other important aspects, calculating the extra pressure drop due to the porous filter is of primary objective. Conventionally this is accomplished through multiple sets of experiments considering possible geometric and operating conditions. The experimental test requires building the prototype at the design stage and testing it for each and every application, therefore, is costly; the computational approach appears to be a
