Fluid-structure interaction phenomena on NACA 4412 airfoil having membrane material
which was partially mounted on both its suction and pressure surfaces were experimentally …

A passive flow control device with a local flexible membrane material over the suction
surface was experimentally investigated with a smoke-wire experiment and time-dependent …

The efficiency of wind turbines can negatively be affected by flow structures such as the
formation of laminar separation bubble or abrupt stall. This can decrease the aerodynamic …

In recent years, leading-edge protuberances have attracted plenty of attention as a passive
method to manipulate flow separation on wind turbine blades. In this paper, an experimental …

In the current study, the aerodynamic performance of NACA 4412 airfoil with sandpaper
which was used as an alternative control device instead of vortex generators was …

Flow separation on blades is the main factor to reduce the power efficiency of vertical axis
wind turbine (VAWT). A bio-inspired flow control device called adaptive flap is considered to …

Aerodynamic characteristics of two-dimensional membrane airfoils were experimentally
investigated in a wind tunnel. The effects of the membrane pre-strain and excess length on …

This paper presents the wind tunnel experimental results to investigate the effects of surface
gradient-of-curvature on aerodynamic performance of a low Reynolds number airfoil Eppler …

In order to suppress the laminar separation bubble and its negative effects on airfoil at low
Reynolds numbers, a partially flexible membrane was utilized on the suction surface of a …

In this paper the flow characteristics and velocity fields over the vertical axis wind turbines
