| Abstract: | In order to research and develop the respirable dust separator satisfied the sample specification of BMRC curve. Various geometries were performed to study inner flow field by commercial computational fluid dynamics(CFD) code Fluent 6. 3. Moreover a quadratic regression model for sampling efficiency was established by regression design technique. Through comparing the prediction model with numerical simulations,it was found that regression design can ensure reliability of calculation model,and significantly raise work efficiency. |
