What is it about?

How to remove pollutant particles? This work uses the W-M fractal function to construct the topography of the polluted wall, explores the formation process of the vortex near the wall during the droplet impact cleaning process, and intuitively describes the relationship between the cleaning process parameters and the vortex between pollutant particles.

Why is it important?

Our findings suggest that the formation of eddy currents between particles plays an important role in the removal of pollutant particles. The cleaning force produced by different cleaning process parameters is also different, which provides a certain basis for the selection of cleaning process parameters.


It is my hope that this article will lead other researchers to consider the random rough wall case formed by pollutant particles when exploring pollutant cleaning.
