Abstract: The purpose of this article is to review some of the novel flow visualization techniques that are particularly suited for studying unsteady flows. While many of these techniques are equally ...

Abstract: The unsteady flow around three-dimensional lifting surfaces undergoing a harmonic pitching motion was studied in a towing tank using the dye-layer technique. Different color fluorescent dyes were ...

Abstract: The unstable response of elastic and viscoelastic surfaces to a turbulent boundary layer was experimentally investigated in an 18-m towing tank. The compliant surface deformation was measured ...

Abstract: Manufacturing processes that can create extremely small machines have been developed in recent years. Microelectromechanical systems (MEMS) refer to devices that have characteristic length of less ...

Abstract: During the past five years, several research programs have been conducted to reexamine the subject of boundary layer interactions with compliant coatings. One of the objectives of the research ...

Abstract: This article presents a review of some recent work that deals with the phenomenon of unsteady separation on two- and three-dimensional lifting surfaces. The presently available experimental data ...

Abstract: This brief article reviews the important advances in the field of flow control that took place during the past few years. This broad area of research remains of great interest for its numerous ...
