| Summary: | n this paper, an improved lattice Boltzmann scheme is used to simulate steady incompressible flow inside a square cavity. The newly improved scheme is applied for driven square cavity. Numerical simulations are carried out for Reynolds number equal to 5000. The governing equation used is the double-population lattice Boltzmann formulation. On the other hand, two-dimensional nine velocity model is used for the computation of velocity field. The results obtained are compared with the results found in the literature reviews. Moreover, the time needed for the solution to converge is recorded. The time obtained is compared with the time required for the conventional lattice Boltzmann scheme to converge. Present study found that the computation time can be reduced without sacrificing the accuracy of the results. |
