The effect of partial slip flow on airfoil performance at high Reynolds numbers is analyzed in this paper. The link between the physical mechanism of drag reduction attained by many devices and the slip length concept has been well assessed in the li

The effectiveness of riblets in reducing friction drag has been well assessed by many experi- ments in flat plate and channel flow in the end of the last century. Both theory and experiments showed that the effect of riblets only depends on the local

International audience; The application of riblets on a typical regional turboprop configuration is discussed in this paper. The effect of the riblets is modeled as a singular roughness problem by a proper boundary condition at the wall. The model, a

More and more interest is set in ice accretion problem, as it affects the global perfor- mances of an aircraft with catastrophic consequences. One of the problems that makes difficult to study this phenomenon is that it is dangerous to fly in ice con
