The interaction of meandering tip vortices shed from a leading wing with a downstream wing was investigated experimentally in a water tunnel using flow visualization, particle image …
Formation flight is one potential measure to increase the efficiency of aviation. Flying in the upwash region of an aircraft's wake vortex field is aerodynamically advantageous. It saves …
A numerical study is conducted to characterize the tip vortex unsteady evolution on a rounded-tip NACA0012 wing of aspect ratio operating at a Reynolds number of R e= 2.0× 10 …
Impingement of a streamwise-oriented vortex upon a fin, tail, blade or wing represents a fundamental class of flow–structure interaction that extends across a range of applications. It …
