摘要(Abstract)：

气液分离广泛采用叶片式分离元件，叶片形式、叶片间距、叶片高度、液滴粒径、液滴含量和主体流速等因素均影响元件的分离性能。采用计算流体动力学(CFD)模拟软件ANSYS FLUENT对3种叶片式气液分离元件(NH-TP、NC-TP和TP叶片)进行数值模拟及对比分析，得到各因素对分离效率及压降的影响，并对叶片的工况适应性进行了分析。结果表明：NH-TP的间距应大于20 mm,否则容易导致压差过大，而NC-TP和TP间距可取10 mm;液滴粒径大于20μm时在各种速度下均可获得较高分离效率，而小液滴仅在理想重力分离和理想惯性分离工况下较高；惯性分离速度下的分离效率与叶片高度无关，主体分离速度低时分离效率随着板高增加而降低；不同形式叶片的最差工况速度不同，但NH-TP在最差工况下仍能保持较高分离效率，对工况的适应能力最好，开槽的NC-TP次之，TP叶片适应能力最差。
