In this paper, the performances of louver concentrator were studied by means of experiment and numerical simulation. A lot of analyse and research works were done to present how louver stucture and flow conditions affected the performances of the concentrator, which included ratio of flux of rich and lean air、 resistance coeffient、 concentration ratio、 separation efficiency. And the optimization louver structure was put forward. It is showed that the virtue of the louver concentrator are good concentration effect、 low resistance、 mezzo air distribution.
