Abstract
In this work, the Lattice Boltzmann Method based on the Multiple Relaxation Time collision operator is employed to solve the governing fluid flow equations. The method is coupled with the Immersed Boundary Method , a robust meshless approach that represents the geometry of interest on a grid distinct from that used for solving the fluid equations. The interaction between the fluid and the solid boundary is modeled through a body force term, which is transferred between the two grid systems via a Dirac delta function. This coupling enables accurate simulation of fluid–structure interactions involving complex geometries. Within this framework, a Large Eddy Simulation approach is implemented using the Smagorinsky subgrid-scale model, allowing the study of high Reynolds number flow regimes without the need for excessive grid refinement. The study then examines the interaction between a circular cylinder and a lamina at a fixed Reynolds number of 104.
