Abstract—The turbulent flow pattern behind the objects induced by shape of solids and its skin-friction occurring, e.g., on the surface of an aircraft, automobiles or the carriage of a high-speed train, is responsible for excess fuel consumption and increased carbon emissions. The environmental, political, and economic pressure to improve fuel efficiency and reduce carbon emissions, and another factors associated with human activities, means that investigating fluid flow in micro scale to reduce skin-friction drag is a pressing engineering problem. This paper is presenting the results of laboratory experiments, studying appearance and magnitude of dynamic pressure in micro scale of subsonic air flow around right cylinder and symmetrical airfoil.
