我们提出、分析和验证带有累积碰撞算子的格子玻尔兹曼模型。分析和数值显示，新模型比基于矩的多重弛豫时间格子玻尔兹曼模型具有更小的误差。我们通过模拟雷诺数从 200 到 10(5) 的球体周围的流动来证明累积格子玻尔兹曼模型的可用性。 (C) 2015 年作者。由爱思唯尔有限公司出版
We propose, analyze, and validate a lattice Boltzmann model with a cumulant collision operator. The new model is analytically and numerically shown to poses smaller errors than a moment based Multiple Relaxation Time lattice Boltzmann model. We demonstrate the usability of the cumulant lattice Boltzmann model by simulations of flow around a sphere for Reynolds numbers from 200 to 10(5). (C) 2015 The Authors. Published by Elsevier Ltd.
