| Abstract: | By applying computational fluid dynamics and acoustic finite element analysis technique,the flow resistance and noise characteristics of air cleaner are simulated and analyzed,in which the flow resistance and sound absorption characteristic of its filter element are also specifically studied.Finally an optimization aiming at reducing the noise of cleaner is performed with the flow resistance characteristic of optimized air cleaner reevaluated. |
