Abstract

Textured surface that provides for drag reduction, and therefore efficiency improvements in a liquid ring pump. At least a portion of the surfaces of the pump that contact fluid therein the pump are textured to control boundary layer separation. The texture can be a plurality of dimples are defined therein the surface. The dimples have a predetermined shape, size, density and pattern.
