Abstract
In this paper, we propose a hybrid lattice Boltzmann method (HLBM) for
solving fluid-structure interaction problems. The proposed numerical approach
is applied to model the flow induced by a vibrating thin lamina submerged in a
viscous quiescent fluid. The hydrodynamic force exerted by the fluid on the
solid body is described by means of a complex hydrodynamic function, whose real
and imaginary parts are determined via parametric analysis. Numerical results
are validated by comparison with those from other numerical as well as
experimental works available in the literature. The proposed hybrid approach
enhances the capability of lattice Boltzmann methods to solve fluid dynamic
problems involving moving geometries.
