摘　　要：旋风分离器具有结构简单、工作稳定可靠、造价低、维修方便等优点，在粉体工业领域应用广泛。旋风分离器的内部流场，属于复杂的三维湍流，同时也是强旋流，具有强烈的非均匀性和各向异性的特点。本文综述国内外旋风分离器内部流场的研究进展，对其内部流场的工作原理、实验研究、数值模拟等方面进行了阐述，探讨了最新的研究动向。There are many advantages in cyclone separators, such as： simple structure, stable and reliable work, low cost, convenient repair. They are widely used in the field of powder industry. The internal flow field of them, which belongs to the three--dimensional turbulent complex, is also a strong swirl, and has the characteristics of strong heterogeneity and anisotropy. Research progress of the internal flow field at home and abroad of them, the working principle, the experimental study of internal flow field, numerical simulation are expounded, the latest research trends are discussed.
