随着Hénical Lattice Gas的发明，人们希望这种新技术能够促进湍流的直接模拟。然而，在过去的几年里，我们已经了解到它的数值精度和计算效率的障碍，这是不容易采取的。晶格气体的工作在引入晶格玻尔兹曼方案时得到了发展。通过适当的改进，该方案提供了鲁棒性和数值精度之间的基本平衡，使我们能够模拟雷诺数高达50000的三维时间相关流动。
With the invention of the Hexagonal Lattice Gas it was hoped that this new technique would facilitate direct simulation of turbulent flow. In the past years, however, we have learned about its barriers on numerical accuracy and computational efficiency, which cannot easily be taken. The work on lattice gases has evolved in the introduction of the lattice-Boltzmann scheme. With the appropriate refinements this scheme provides the essential balance between robustness and numerical accuracy and enables us to simulate three-dimensional time-dependent flows at Reynolds numbers up to 50000.
