Abstract

Simulating the turbulent flows inside practical combustors is an important computational challenge that demands both accuracy and efficiency. In this work, a lattice Boltzmann-based large eddy simulation (LES) flow solver has been developed and validated for a non-reacting flow in an experimental swirl-stabilized combustor. Our in-house solver uses the immersed boundary method on a non-uniform Cartesian mesh to model complex geometries and the multiple-relaxation-time collision model for numerical stability. When compared to experimental data, the LES results show good agreement for mean velocity profiles. This study demonstrates the predictive capability of the lattice-Boltzmann-based LES framework for turbulent flow studies.
