Asymptotic analysis of LB for fluid-structure interaction: boundaries, forces and coupling schemes

A. Caiazzo

Abstract
Recent development of LB schemes offer a variety of algorithms to incorporate different boundary conditions and deal with the fluid-solid interactions. We discuss some of these issues from the point of view of asymptotic analysis [1, 2], in particular discussing the consistency of the conditions at the fluid-solid interface for no-slip conditions, immersed boundary approaches, Lees-Edwards boundaries and force evaluation via Momentum-Exchange [3, 4]. Finally, asymptotic analysis of coupling scheme will be discussed.
