Résumé

Abstract This work reports a direct numerical simulation study on submerged-solid and fluid flows, using a novel variant of the immersed boundary method under the aegis of Gerris solver. The method handles three-dimensional 6 degree-of-freedom motion of immersed solids of any number and of any shape under the influence of flow. We use it here to study the hydrodynamic interactions (between solid-wall and between soids) in a constant shear flow at low Reynolds number. The study calculates the influence from the solid- wall distance, solid-solid distance and ellipsoid geometrical characteristics. Distinct patterns emerge and the discussion focusses on improving our current understanding on solid migration due hydrodynamic interaction.
