The paper is an example of computer simulation in mechanical engineering. Velocity field in a hydrocyclone are determined numerically, because for direct measurements it is difficult to achieve them. The numerical simulation of 3D fluid dynamics based on the k-eps RNG model of turbulence in the hydrocyclone with the injector, containing 5 tangentially directed nozzles is considered. It is shown that the direction of movement of injected fluid in the hydrocyclone depends on the water flow rate through the injector. The calculations show in accordance with the experiments that the dependence of the Split-parameter on the injected water flow rate has a non-monotone character associated with the ratio of power of the main flow and the injected fluid.
