The corrugated pipe is widely used in figure heat exchangers. For the reason of large temperature difference between the gas in the pipe and the cold wall, particles may deposit on the wall, and make some adverse effects, such as poor cooling effect and the block in the pipe, especially in the pipe node. To solve the problem of deposition in the pipe, this paper will apply the model of DRW to calculate the trajectory of the micro particles. In this paper, the trajectories of particles with different sizes in a corrugated pipe are calculated, and the effects of structure parameter and inlet velocity on the trajectories of particles are studied. The conclusion can provide a theoretical basis for solving the deposition in corrugated pipes.
