As a successful example of non-boundary conforming methods, the Cartesian mesh is utilized for resolving flow field in IBM. The effect of boundary is replaced by the body force density which influences flow phase around the boundary. The governing equations with this force density are solved on the whole computational domain including the exterior and interior of the boundary. On the other hand, as an alternative CFD tool, the lattice Boltzmann method (LBM) has gained wide range applications recently. Since the Cartesian mesh is also employed in LBM, an efficient solver can be generated by combining IBM with LBM, which is called IB-LBM. Some efforts have been made in this aspect and the achievement is obvious. However, there are still some shortcomings in this newly developed approach. In this work, two major improvements were made. Firstly, a new version of IB-LBM was proposed in order to strictly satisfy the non-slip boundary condition. In the conventional IB-LBM, the non-slip boundary condition is not enforced, and is only approximately satisfied at the converged state. As a consequence, the accuracy of solution is reduced, and the situation of streamline penetration to solid boundary is present. To overcome this drawback, a boundary condition-enforced IB-LBM was developed. Different from the conventional IB-LBM in which the body force is computed in advance, the unknown body force is employed viii in present method. Such force is resolved by enforcing the non-slip boundary condition. Applying the developed approach, the two-dimensional (2D) stationary and moving boundary flow problems, as well as particulate flow problems, were simulated. Since the non-slip boundary condition is enforced, no flow penetration happens and the accuracy of resolution is improved. All the obtained numerical results are compared well with previous experimental and numerical results. In the application of IB-LBM, the non-uniform mesh is usually employed in order to improve the computational efficiency. To apply LBM on the non-uniform mesh, many variants of LBM can be chosen. A simple way is to use Taylor series expansion and least squared-based LBM (TLLBM). Its final form is an algebraic formulation, in which the coefficients only depend on the coordinates of mesh points and lattice velocity. As compared to the standard LBM, the drawback of TLLBM is that additional memory is required to store the coefficients. Due to the limitation of virtual memory, it is not easy to apply TLLBM in three-dimensional (3D) simulations. To overcome this difficulty, an efficient LBM solver based on the one-dimensional interpolation was developed. As compared to TLLBM, much less coefficients are calculated. Combing with this efficient LBM solver, the new IB-LBM was easily extended to 3D simulation. The 3D flows around complex stationary and moving boundaries were simulated. The obtained numerical results are agreed well with the results and findings in the literature. ix References Fedkiw RP, Aslam T, Merriman B, and Osher S, A non-oscillatory Eulerian approach to interfaces in multimaterial flow flows (the ghost fluid method), J.
