Coating flow on cylinder

WebAn analysis of steady coating flow of a thin film of a viscous fluid on the outside of a uniformly rotating horizontal circular cylinder in the presence of an irrotational airflow with circulation shows that the presence of the airflow can result in qualitatively different behaviour of the fluid film from that in classical coating flow. WebAug 23, 2024 · Two types of drag reduction can be seen: (1) when the relative length of the microfiber, k / D, is less than 1.8%, and the coating is applied before flow separates over the cylinder; and (2) k / D is over 3.3%, and the coating is applied after the flow separation location on the cylinder.
