Potential Flows

Abstract

As the discussions in Sects. 4.1 and 4.3 have already shown, solid walls and discontinuities in the tangential velocity represent surfaces from which angular velocity $\left( {\vec{\omega } = {\text{curl}}\,{{\vec{u}} \mathord{\left/ {\vphantom {{\vec{u}} 2}} \right. \kern-0pt} 2}} \right)$ diffuses into the flow field. Since the widths of the developing regions (boundary layers) tend to zero in the limit Re → ∞, the flow can be treated within the framework of potential theory.
