Fluid–body interactions: clashing, skimming, bouncing

Abstract

Solid–solid and solid–fluid impacts and bouncing are the concern here. A theoretical study is presented on fluid–body interaction in which the motion of the body and the fluid influence each other nonlinearly. There could also be many bodies involved. The clashing refers to solid–solid impacts arising from fluid–body interaction in a channel, while the skimming refers to another area where a thin body impacts obliquely upon a fluid surface. Bouncing usually then follows in both areas. The main new contribution concerns the influences of thickness and camber which lead to a different and more general form of clashing and hence bouncing.
