Abstract
This study explores the application of the Lattice Boltzmann Method (LBM) for modeling anisotropic turbulence through Implicit Large Eddy Simulation (ILES). The aim of this paper is to validate the LBM-ILES approach in modeling the complex flow dynamics within cyclones, a common device in several engineering applications. By implementing an implicit approach, we aim to solve the turbulent structures without the need for additional turbulence models. The results demonstrate that the LBM-ILES approach successfully models the Rankine-type velocity profile characteristics in cyclones, providing detailed insights into flow patterns and validating the model against experimental data. This research highlights the potential of LBM in advancing turbulence modeling techniques, offering a robust tool for future studies in turbulent flows.
