A kind of new turbulent flow in annular square channel with two cooled wall was designed on basic thermophoresis principle.
依据热泳基本原理，设计了一种新型湍流方环形双壁冷却式通道。
The present analysis shows that the influence of the near-wall effect and the evaporation on the particle thermophoresis can not be ignored.
研究表明，近壁效应及蒸发对颗粒热泳的附加影响是不容忽视的。
Although the thermophoresis force could affect the 50-micron particle, the concentration did not change as large as 2-micron particle because of the large mass and the wall effect.
热泳力对粒径为50微米的颗粒也有影响，但是由于颗粒的质量较大，再加上壁面效应，其作用效果远没有2微米颗粒明显，仅在近壁区颗粒的浓度略有升高，而其它部分基本不变。
