摘　　要：介绍了旋流器两相流分离的湍流涡动性质。根据修正的旋流器内k-ε湍流数学模型,分析了旋流场内部湍流度及相对湍流度对湍流场流动分布、湍流脉动和分离介质所产生的影响。利用流体计算软件对旋流器内部湍流场、分离介质运移轨迹及切向速度场分布进行了数值模拟。Turbulent characteristic of two separating flow was introduced, with k-ε mathematic model being established and revised inside a hydrocyclone. Turbulent rate and relative rate influencing vortex field distribution of fluid flow, turbulent pulsation and separation medium inside the hydrocyclonic field were analyzed. By means of fluid computation soft, the numerical simulation of turbulent field model, the moving tracks of separation medium and the distribution of tangential velocity were analyzed inside the hydrocyclone. The results of testing validate a proper and reliability of numerical simulation.
