چکیده

In this study the influence of the exit tube geometry on the overall flow properties of cyclones is investigated using detached eddy simulation. The results for different exit pipe shapes and lengths reveal that under certain conditions the outlet has an upstream effect on the flow behaviour within the cyclone. This can in turn result in poor build-up of swirl in the crucial region of the cyclone and substantially reduce the efficiency of the cyclone as a particle-separation device.

Particle Collection and Concentration for Cyclone Concentrators

Four cyclone concentrators were designed and fabricated to compare their particle separation and concentration behavior, such as the major, minor, outlet, and wall deposition fractions. Two of the cyclone concentrators were the conventional type, with the minor flow tube connected to the particle outlet at the bottom of the cyclone. The others were modified cyclone concentrators with a gap betw...
