| Abstract: | In this paper, we analyzed the cleaning principle of the two-fan cylinder screen cleaning mechanism, surveyed the flow field of the cleaning mechanism in two conditions. With computer technology, we drew the figures of the flow field and the figures of the wind speed's distribution. On the basis of the previous work, we analyzed the relationships between flow field and cleaning performance, and made clear the influences of the changing of the fan's location and motion parameters on cleaning performance. We pointed out the flow field's ideal condition and the methods to improve the cleaning performance. |
