摘要
利用CFD软件FLUENT6.3模拟三维稳态流动,对引入二次流的旋风分离器各项参数进行了优化设计,采用RSM模型模拟气相有旋流动,利用DPM离散模型进行颗粒相跟踪。通过比较优化前后流场特性,证明二次流有助于提高旋风分离器的分离效率及流场稳定性,不同的进风角度和速度会得到不同的分离效率,为新一代旋风分离器的开发与制造提供了参考依据。
A new type of gas-cyclone with a secondary flow injection was studied in this paper. The numerical simulation describes the flow field in the cyclone by using Reynolds stress model （RSM） with Fluent6.3. The discrete phase model （ DPM） is also used to predict the trajectories of the particles, and the predictions are compared with the conventional one. The results prove that secondary flow injection is helpful for increasing the separation effect and the stability of the flow field in the cyclone. Different entering angle and velocity will obtain different separation effect. This study proposed a reference and guidance for a new generation of cyclone development and manufacture.
