When cross-shaped flat plates are placed on a bluff body aligned with the flow, longitudinal vortices form near the intersection. Our longitudinal-vortex-driven cylindrical-blade wind turbine uses these vortices as driving force, and we study it to promote a new wind-power concept.

Everyday materials such as cosmetics, detergents, and slurries can start to flow when sufficient force is applied. These are called complex fluids. We investigate their properties using a range of experimental and analytical approaches.
