WebbThe SHSLBM was developed for simulating incompressible viscous flows and showed great performance in numerical stability at high Reynolds numbers, which means that this model is capable of dealing with turbulent flows by adding the turbulence model. Therefore, the LES model is combined with SHSLBM. Webbbased method that numerically solves the Boltzmann equation as opposed to con-ventional DNS methods that are based on the Navier-Stokes (NS) equations. The advantages of the LBM are its simple implementation, its ability to handle complex geometries, and its scalability on modern high-performance computers.
