000014385 520__ $$2eng$$aLiquid-infused surfaces are textured surfaces that have a lubricating liquid impregnated in the surface features. When these surfaces are exposed to the flow of an immiscible liquid, it is possible to achieve substantial drag reduction in fully turbulent flow. Liquidinfused surfaces may overcome some of the shortcomings associated with conventional superhydrophobic surfaces, namely failure under turbulent flow fluctuations and conditions of high hydrodynamic pressure. Results are presented for turbulent Taylor-Couette flow with longitudinal grooves. A number of different lubricating liquids are tested, and we find a strong dependence on the ratio between the viscosity of water and that of the lubricating liquid. The drag reduction, remains fairly constant over the Reynolds number range tested (100 ≤ Reτ ≤ 140) with a maximum of about 14%, as reported by [6]. The current study extends this previous work to examine the effects of changing the characteristics of the surface features.
