摘要
定性分析了非稳态旋进涡核在旋风分离器流场中的运动形式及其对流场的影响。按照涡丝在流场中产生诱导速度的原理 ,提出了旋风分离器流场中有旋进涡核存在时流场的计算方法 ,通过计算值与实测值的比较发现两者吻合较好。
The motion of precessing vortex core (PVC) in a cyclone separator is described and the influence of PVC on the flow field in the cyclone separator is analyzed. A method to calculate the velocities in flow field concerning with the influence of the PVC is deduced by meanings of vortex induced velocity. The result shows good agreement comparing with the calculating and the experimental data.
