This study is numerical analysis on flow characteristic in a standard cyclone dust separator. The cyclone dust separator is widely used in a industrial applications as a method for dust removed from gases. In cyclone chamber, a very complex flow field is formed, involving the interaction between highly swirling velocity and turbulent field. Numerical analysis with computational fluid dynamics(CFD) was carried out to investigate the working fluid that flow into cyclone dust separator. Helical entry type was increasing flow rate compared with tangent entry type. And according to increasing pressure difference was increased fan power. But, helical entry type was high performance dust separator, in comparison with tangent entry type.
