STUDY OF FLOW AERODYNAMICS AND DUST FORMATION INTENSITY WHEN USING A SEMI-PERMEABLE PROTECTIVE BARRIER

The removal of dust from contaminated surfaces at industrial sites poses a threat to workers' health. Such dust formation is particularly intense at industrial sites where there are coal piles, bulk material dumps, and contaminated surfaces. To reduce the intensity of dust formation, protective barriers of various shapes are used near dust-forming surfaces. The presence of a protective barrier changes the aerodynamics of air flows at the site and reduces the intensity of dust formation from contaminated surfaces. Therefore, determining the effect of a protective barrier on the intensity of dust formation is an important task.

The article presents the results of laboratory studies to determine the dynamics of dust formation intensity and the aerodynamics of air flow at an industrial site using a partially perforated protective barrier. Based on the results of the experiment, empirical models were developed to estimate the intensity of dust formation and the air flow velocity behind the barrier. Numerical models were developed to predict the intensity of dust pollution in the air at an industrial site.
