Abstract

The large eddy simulation method is used to simulate the flow field in the hydrocyclone with double conical structure, and the result shows that existence of the secondary swirl has a vital effect on the separation. The tangential velocity in the swirling flow could be regarded as a kind of rankine-like vortex. And the gradient near the axis is large. At the same time two-way velocity gradient is significantly larger. Velocity near the wall gradually decreases. The flow field of random fluctuation affects the oil column size and its stability. This instability in turn intensifies the turbulent in flow field, which leads to the reduction of the separating efficiency.
