| 摘 要： | 依据热泳基本原理 ,设计了一种新型层流方环形双壁冷却式通道。经过计算 ,该类型通道比一般管通道有着较高的脱除可吸入颗粒物的效率。同时 ,在不同的气流进口温度下 ,利用速度温度充分发展流与速度温度正在发展流的有不同热泳沉积效率工况 ,可以达到较高的沉积效率。通过结构设计 ,可以达到较高的可吸入颗粒物脱除效率 ,是值得进一步探索的新路子。

| Abstract: | A kind of new layer flow cycle channel with two cooled walls was designed on basic thermophoresis principle.This kind of channel has a higher cumulative efficiency for removing inhaled PM2.5 than usual channel through calculation.In the meantime,the higher cumulative efficiency for removing inhaled PM2.5 will be obtained by taking into account developing flow and developed flow of speed & temperature at different inlet gas temperature conditions.It is a new way that is worth researching further. |

| Keywords: | two cooled walls thermophoresis inhaled particle matter and cumulative efficiency |
