Laminar Flow Past Bodies Under Perfect Slip

Abstract

Current experience conducted at Dornier System on special solid-surface treatment have prompted a study on the fluid dynamic implications of perfect-slip flow. Numerical results on incompressible fluid flows past thin elliptic cylinders at various angles of attack and at moderate Reynolds numbers show that flow separation, instability, and vortex shedding occur also under the perfect-slip condition. Of particular interest is the generation and spreading of an initial vortex after the abrupt start of an airfoil. The circulation theory of lift for potential flows is also applicable to perfect slip. Thus, lift exists so that flying under perfect slip is possible.
