Abstract

Super-hydrophobic effect involves capture of gas bubbles in pores of a solid wall, which separates liquid from the solid, resulting in the reduction of the shear drag experienced by the liquid. This effect occurs in the presence of two phases. A similar effect might be produced by creating separation bubbles made of the same fluid through proper shaping of the surface. Use of transverse grooves with a sufficiently short wavelength creates the required flow topology. The shear drag decreases by up to 50% compared with the smooth wall but the interaction pressure drag increases, resulting in only minor reduction in the overall drag. Proper shaping of the grooves may reduce the interaction pressure drag. Copyright © 2012 by ASME.
