Test of the Possible Application of the Half—Way Bounce—Back Boundary Condition for Lattice Boltzmann Methods in Complex Geometry
The way of handling boundary conditions with simple bounce-back rule in the lattice gas and lattice Boltzmann method had been considered as one of the advantage compared with other numerical schemes.The half-way bounce-back rule inherits the advantage of the bounce-back rule and improves the accuracy to the second-order on flat boundaries.In this paper,we test the possible apphcation of the half-way bounce-back rule to the system with complexgeometry.Our simulation results show that the haft-way bounce-back rule is a good boundary condition in the problems without emphasis on accuracy.
