Drag reduction on a patterned superhydrophobic surface.
We present an experimental study of a low-Reynolds number shear flow between two surfaces, one of which has a regular grooved texture augmented with a superhydrophobic coating. The combination reduces the effective fluid-surface contact area, thereby appreciably decreasing the drag on the surface and effectively changing the macroscopic boundary condition on the surface from no slip to limited ...
متن کاملDrag reduction properties of superhydrophobic mesh pipes
Even with the recent extensive study into superhydrophobic surfaces, the fabrication of such surfaces on the inside walls of a pipe remains challenging. In this work we report a convenient bi-layered pipe design using a thin superhydrophobic metallic mesh formed into a tube, supported inside another pipe. A flow system was constructed to test the fabricated bi-layer pipeline, which allowed for ...
متن کاملSustainable drag reduction in turbulent Taylor-Couette flows by depositing sprayable superhydrophobic surfaces.
We demonstrate a reduction in the measured inner wall shear stress in moderately turbulent Taylor-Couette flows by depositing sprayable superhydrophobic microstructures on the inner rotor surface. The magnitude of reduction becomes progressively larger as the Reynolds number increases up to a value of 22% at Re=8.0×10(4). We show that the mean skin friction coefficient C(f) in the presence of t...
متن کاملLarge-area superhydrophobic nanofiber array structures for drag reduction
Surface with a static contact angle (CA) greater than 150° are in general defined as superhydrophobic surfaces. Superhydrophobic surface have great potentials in fundamental research,[1-5] and also wide practical applications in the production of textile, microfluidics, self-cleaning surfaces, building glass, windshields of cars, ships hulls, pipes and the satellite antenna surfaces.[6] Superhy...
متن کاملTerminal velocity and drag reduction measurements on superhydrophobic spheres
Super water-repellent surfaces occur naturally on plants and aquatic insects and are created in the laboratory by combining micro or nano-scale surface topographic features with hydrophobic surface chemistry. When such types of water-repellent surfaces are submerged they can retain a film of air (a plastron). In this work, we report measurements of the terminal velocity of solid acrylic spheres...
