Abstract


The behavior of a vortex generated by a moving object subjected to vibration and fluidic noise has been investigated. The authors performed the PIV measurement for vortex flow in the vicinity of a wall of the elastic NACA0010. We clarified quantitatively the effect of elastic deformation to the developing process of vortices generated in the vicinity of a wall. The positive of second invariant of the velocity gradient tensor depends on the relative acceleration.
