不同断面下的截留捕尘效率比较研究

Research on Dust Collection Efficiency about Potential Flow Around Three Kinds of Section

分析了流体绕圆柱体、平板、圆弧板断面作势流流动时的流函数,给出了三种流动时的截留捕尘效率。研究结果表明,在相同的投影面积下,绕圆弧板的截留捕尘效率最大,绕圆柱体的最小;对于圆弧板断面,圆弧板的曲率半径越大,捕尘效率越高。

Flow functions around three different kinds of section, i.e., circle,flat,and arc profile were analyzed. Calculation on the dust collection efficiency was carried out respectively. The results showed that the dust collection efficiency around arc is maximum and the circle is minimum at the same projective area.
