Generalization of composite dynamics for the lattice Boltzmann method
arxiv(2024)
摘要
A generalized composite dynamics (GCD) framework is presented for the lattice
Boltzmann method (LBM). It leverages synergies of various simple collision
operators to model complex physical processes. The framework is validated by
recovering semi-permeable fluid flow methods. It provides mathematical
justification for the incorporation of forces, addressing a gap in the
literature. The versatility of this framework is demonstrated by analyzing a
flux boundary condition. The GCD framework opens innovative possibilities for
simulating complex physical processes using LBM.
