The effect of a surface trip wire on the flow around a sphere is experimentally investigated at subcritical Reynolds numbers ofRe= 0.5 × 105– 2.8 × 105based on the free-stream velocityU∞and sphere diameterd. By varying the streamwise location (

In the present study, we perform a wind-tunnel experiment to investigate the aerodynamic performance of a gliding swallowtail-butterfly wing model having a low aspect ratio. The drag, lift and pitching moment are directly measured using a 6-axis forc

In this review, we present control methods for flow over a bluff body such as a circular cylinder, a 2D bluff body with a blunt trailing edge, and a sphere. We introduce recent major achievements in bluff-body flow controls such as 3D forcing, active

Wake-induced boundary-layer transition on a NACA0012 airfoil with zero angle of attack is experimentally investigated in periodically passing wakes under the moderate level of free-stream turbulence. The periodic wakes are generated by rotating circu

Active control of flow over a sphere at $). For the forcing frequencies smaller than this critical frequency, the drag is either nearly the same as, or slightly smaller than, that without forcing. The critical forcing frequency is found to be closely

The effect of a localized time-periodic wall motion on a turbulent boundary layer flow is experimentally investigated in this study. A part of the wall is replaced with a circular membrane (560 wall units in diameter) which moves up and down periodic

Hot-wire measurements are performed in boundary-layer flows developing on a NACA 0012 airfoil over which wakes pass periodically. The periodic wakes are generated by rotating circular cylinders clockwise or counterclockwise around the airfoil. The ti

The use of triangular shaped piezoceramic actuators in the near-wall region of turbulent shear flows is described. These actuators are very thin so that they can be flush mounted on the wall which greatly simplifies their application. The piezocerami

The sailfish and swordfish are known as the fastest sea animals, reaching their maximum speeds of around 100 km/h. In the present study, we investigate the hydrodynamic characteristics of these fishes in their cruise speeds of about 1 body length per
