HYDROELASTICITY PROBLEM FOR AN ELASTIC PLATE IN A VISCOUS INCOMPRESSIBLE LIQUID

Abstract

In this paper, we discuss the two-dimensional flow problem over a linearly  elastic plate, with a viscous fluid. The velocity and pressure fields the plate are  studied as well as the dynamics of the plate in the elastic-deformed state. In the  case of a viscous fluid the separation occurs at the ends of the plate, which causes  deformation of the elastic plate and, consequently, a change in its geometry, which  in turn affects the impulse of the separated flow. The dynamics of the expected  flatter event at different flow velocity conditions are studied.
