Control of Laminar-Turbulent Transition on a Swept Wing Using Surface Microreliefs

摘要: The possibility of laminarization flow around a swept wing using surface microreliefs in the form riblets and separate plates (winglets) set at an angle to external streamlines is theoretically investigated. This relief shown reduce crossflow velocity boundary layer due change direction near-wall streamlines. On basis very simple models based on analysis period-averaged increase Reynolds number laminar-turbulent transition obtained microrelief estimated. reasonable parameters for experimentally investigating effectiveness proposed technique controlling are determined.
