Abstract
The internal temperature will change depending on operation conditions and material of cyclone dust collector. This
study compares the results of collection efficiency and temperature distribution on the different heat flux at wall of
dust collector. The previous researcher\'s experiment results were used to confirm the reliability of CFD(Computational
Fluid Dynamics) model. Based on this verified CFD model, we extended the analysis on the cyclone dust collectors.
In CFD study, we used RNG k-epsilon model for analysis of turbulence flow, fluid is air, the velocity at inlet is 10 Éõ,
the temperature of air is 600 ¡É. Because of the difference of outer vortex and inner vortex temperature, the collection
efficiency will reduce with the increase of heat flux, showed the highest collection efficiency at heat insulation.
