采用标准k －ε模型、雷诺应力模型（RSM）以及k － w模型对旋风分离器内部湍流流场进行了数值模拟。对比了采用两种不同的离散格式时的计算表现，分析了不同近壁模型对于模拟结果的影响。通过数值解与实验值进行的对比发现采用雷诺应力模型较k－w模型，k－ε模型能更准确地模拟分离器内强旋流场。

Numerical simulation of swirling flow in a cyclone separator was conducted using stand‐ard k -εmodel ,Reynolds stress model (RSM ) and k - w model .The performances of using two convective term discretization schemes and variant near wall treatments were also studied in pres‐ent investigation .It was found that the numerical results predicted by using RSM were closer to the experimental data than those results predicted by using standard k -εand k - w models .
