The effect of isolated roughness elements on transition in attachment-line flows
Abstract
Current knowledge concerning the tripping to turbulence of an attachment-line boundary-layer flow under low-speed conditions is summarized and compared with criteria for tripping in the incompressible, zero pressure-gradient, flat-plate flow. Important similarities and significant differences are illustrated and discussed.
