中文摘要：

在在不同条件下面的充分发达的 laminarflow 的 nanoparticle 免职的数字学习被介绍。粒子的直径从 20 nm 到 200nm，密度是 1060 kg/m~3。计算结果证明小粒子存款在墙更容易出现。更多的大粒子比在上面的墙上在底部墙上扔。在薄片状的条件下面，扔的粒子的数字独立于流动速度。流动区域越小，粒子越在墙上扔。粒子在流动仍然保持越长，粒子越在墙上扔，并且更大在底部墙和上面的墙上扔的粒子的数字之间的差别。

英文摘要：

The numerical study of nanoparticle deposition in a fully developed laminar flow under different conditions is presented. The diameter of the particles ranged from 20 nm to 200 nm and the density was 1060 kg/m3. The calculated results show that the small particles deposit on the wall surface more easily. More large particles deposit on the bottom wall than on the upper wall. Under the laminar conditions, the number of particles that deposit is independent of the flow velocity. The smaller the flow region is, the more the particles deposit on the wall. The longer the particles remain in the flow, the more the particles deposit on the wall, and greater the difference between the number of particles depositing on the bottom wall and the upper wall.
