Numerical analysis of hydroabrasion in a hydrocyclone

2016-4-6 A typical hydrocyclone as depicted in Fig. 1 consists of a cylindrical body, a conical body, open discharge at the bottom called the underflow outlet, a tangential inlet to the cylindrical part of the cyclone body, and an overflow discharge part. The cylindrical body is closed on its top with a plate through which passes an axially located overflow pipe, which is called the vortex finder
