Numerical Analysis of dustproof effect of windbreak net for Coal Yard

Abstract

This article indicates that windbreaks are efficient barriers to reducing or redirecting wind velocity to prevent coal dust transfer by comparing several dustproof techniques and investigating the coal dust pollution status of the coal yard in coastal port. The dustproof principle is analyzed accordingly, and numerical simulation of air flow distribution after windbreak net is performed to obtain the main parameters of the net and the result suggests using windbreak net as main approach, combined with dry or wet method, as well as shelterbelt, and the best scheme of designing the windbreak net is put forward.
