Abstract

The work purpose is to determine the impact of a rough surface on the airflow around it, depending on the degree of the surface roughness.

The experimental research of the process of air stream flowing around samples of flat and rough surfaces has been performed. The experimental results have been compared with theoretical ones obtained by executing a simulation of the considered process which is based on RANS equations.
