| 摘 要： | 利用计算流体动力学软件FLUENT6.2.16对壁面粗糙度不同的旋风分离器内流场进行了数值模拟,得到了切向速度、轴向速度、径向速度和静压力分布规律。旋风分离器内的切向速度随着壁面粗糙度的增大而明显减小;轴向速度没有明显的规律性变化,只在上部筒体涡核区轴向速度增加,削弱了涡核区滞留现象;在流场大部分区域径向速度随粗糙度的...

| Abstract: | The FLUENT6.2.16 software is used to simulate the flow field in cyclones.The distributions of the tangential velocity,axial velocity,radial velocity and static pressure are presented at the different wall roughness.The tangential velocity decreases evidently with the increase of wall roughness.The axial velocity has no obvious regular variety,but increases in the vortex core region of the upper part of the cyclone body,and the retention phenomenon in the vortex core region is weakened.The radial velocity de... |
