文摘
- •
A simplified thermal lattice Boltzmann method (STLBM) is proposed in this paper.
- •
It is derived from macroscopic equations recovered from lattice Boltzmann equation.
- •
It is shown theoretically and numerically that STLBM is unconditionally stable.
- •
As compared with conventional thermal LBM, STLBM needs much less virtual memory.
- •
STLBM can well simulate incompressible thermal viscous flows.
