摘要
利用Fluent软件提供的RSM模型,使用Simplec算法,对对称多入口型旋风分离器进行数值模拟。通过模拟,分析旋风分离器内的切向速度场、轴向速度场及压力场的分布。结果表明,对称性的结构有助于对称流场的形成,从而保持流场的稳定;切向速度分布有着明显的驼峰特征,轴向速度分布分为上行流、下行流区域,压力为顺压分布。
Using the RSM model,a Simplec algorithm provided by Fluent for simulating the symmetric and multi-inlet cyclone,the fields of tangential velocity,axial velocity and pressure in the cyclone are analyzed.The result shows the symmetric structure is helpful to form symmetric flow field,and to maintain the stability of the flow field.The tangential velocity distribution has a clear hump characteristic.The axial velocity is divided into upstream and downstream areas.The pressure is gradually outward high.
