LBM-LES in Ideal 3D Lid-Driven Cavity Flow Problems

Through this chapter, readers will learn the first simulation case, the 3D lid-driven square cavity flowBuilt environmentlid-driven cavity flow at a low Reynolds number, a simple problem but a prototype for many built environment issues. The readers will know the basic parameters and boundary conditions required for LBM-LES simulation. The readers will also know the velocity results under different Reynolds numbers and the consistency comparison with the classical FVM-LES. In addition, the computational time and parallel computational efficiency of LBM-LES and FVM-LES are discussed.
