Susanne Falk,Christina Klug,Maike Reimerwith an airfoil surface, is important in many applications ranging from wind turbines and cooling fans to aircraft and submarines. This chapter presents an introduction to the major mechanisms of airfoil noise production. We begin with a review of leading edge noise that is produced by the interacti

Annekatrin Niebuhr,Anne Otto,Anja Rossen,Christian Teichertfollowing three decades. As a result, it is now believed that compliant coatings, if suitably fabricated mimicking dolphins’ skin, could delay the transition of the laminar boundary layer to turbulence, therefore resulting in a substantial drag reduction. As for the use of compliant coatings in the

This article addresses the question which factors influence the geographical distance between school location and university. For the analyses, we employ a mobility measure of geographical distance (in kilometres) between the university and the sch
