This Letter reports a validation of a lattice-Boltzmann approach following the Taylor–Green Vortex benchmark presented at the 19th International Congress on Numerical Combustion and recently reported by Abdelsamie et al. [“The Taylor–Green vortex as a benchmark for high-fidelity combustion simulations using low-Mach solvers,” Comput. Fluids 223, 104935 (2021)]. The lattice-Boltzmann approach, despite having a time step bound by an acoustic Courant–Friedrichs–Lewy condition, provides results faster than the low-Mach solvers which performed to the benchmark. Such a feat is made possible by the fully explicit nature of the method and indicates very high potential for practical applications.

对反应流的格子玻尔兹曼求解器进行基准测试：该方法是否值得为燃烧付出努力？

这封信报告了根据在第 19 届国际数值燃烧大会上提出并最近由 Abdelsamie等人报告的 Taylor-Green Vortex 基准对格子玻尔兹曼方法的验证。[“泰勒-格林涡旋作为使用低马赫求解器进行高保真燃烧模拟的基准，”计算。流体223 , 104935 (2021)]。尽管具有受声学 Courant-Friedrichs-Lewy 条件约束的时间步长，格子-玻尔兹曼方法提供的结果比执行基准的低马赫求解器更快。该方法的完全明确性质使这一壮举成为可能，并表明实际应用的潜力非常大。
