摘要:In this paper, an improved immersed boundary-lattice Boltzmann method based on the force correction technique is presented for fluid-structure interaction problems including the moving boundary interfaces. By introducing a force correction coefficient, the non-slip boundary conditions are much better enforced compared with the conventional immersed boundary-lattice Boltzmann methods. In addition, the implicit and iterative calculations are avoided; thus, the computational cost is reduced dramatically. Several numerical experiments are carried out to test the efficiency of the method. It is found that the method has the second-order accuracy, and the non-slip boundary conditions are enforced indeed. The numerical results also show that the present method is a suitable tool for fluid-structure interaction problems involving complex moving boundaries.
