The aim of the work is to determine the effect of a rough surface on the airflow flowing around it, depending on the degree of roughness of this surface. Experimental visualization of the flow of air around samples with various rough surfaces is carried out. The experimental results are compared with the theoretical results obtained as a result of modeling this process based on the RANS system of equations.
