A Flow Study in the Cyclone with Particle Separations

Popis výsledku v původním jazyce

Unsteady turbulent flows with solid particles of different sizes in the cyclone were studied numerically and experimentally. The grid studies and influence of the boundary condition prescription on the flow behavior in the cyclone and the effectiveness of the particle separation were studied firstly numerically. The turbulent flow was calculated by means of Large Eddy Simulations and this flow problem was calculated parallel using eight processors. It was found theoretically that pressure at the bottom outlet of the cyclone has a significant impact on the particle separation. This impact of the pressure at the cyclone function was examined also using experiments and pressure distributions for different flow rate intensities for several locations in the cyclone were determined. These experimental results can be used for a validation of numerical results. Furthermore, the larger losses were observed in the immersion tube due to higher flow velocity and impulse exchange in the vortex core.
