Sand screens that are widely used in petroleum industry, can fail due to erosion. Since carrying fluid type can have a considerable effect on erosion, in this study, dense discrete phase model (DDPM) was utilized to model sand screen erosion using a CFD-based technique under air, water, and oil flows with four different sand types. The results showed that, erosion was much greater in liquid flows than in air flows. For liquids flows, erosion increases as the uniformity and the sorting coefficients of sand decrease. It has been concluded that, when sand contains various sizes under a certain fluid type, the significance and contribution of particles related parameters on erosion depend on sorting and uniformity of the produced sand.

广泛用于石油工业的防砂筛可能会因侵蚀而失效。由于携带流体类型会对侵蚀产生相当大的影响，因此在本研究中，采用致密离散相模型 (DDPM)，使用基于 CFD 的技术在四种不同砂类型的空气、水和油流下模拟砂筛侵蚀。结果表明，液体流中的侵蚀比空气流中的侵蚀大得多。对于液体流，侵蚀随着沙子的均匀性和分选系数的降低而增加。结论是，当砂子在某种流体类型下含有不同尺寸时，颗粒相关参数对侵蚀的重要性和贡献取决于所产生砂子的分选和均匀性。
