Interfacial hydrodynamic slippage is controlled by two factors say physical structure and chemical composition. Various studies have been conducted experimentally which try to connect the physical structure of the surface and its chemical property on the interfacial wettability. One such example is the Tunable wettability in surface-modified ZnO-based hierarchical nanostructures . In which vertically aligned Nanoneedles and Nanonails were employed as a platform to determine the effect of surface structure. According to which a variation in static contact angles were observed as the cap size the nanonails constantly increased. Starting with a contact angle of 104° the contact angle first increases and then decreases, which means that the slip length first increases and then decreases. The increase in slip length reduces the drag, which has immense application in the aerodynamic field. This paper investigates the relation between the chemical wettability and aerodynamic drag by performing MD simulations of couette flow with varying fluid-surface interaction. © The Authors, published by EDP Sciences, 2017.
