模拟复杂流动中的湍流输运和混合是计算流体动力学（CFD）的巨大挑战。这本可读性很强的书向读者介绍了尊重湍流物理复杂性的建模水平。它研究了从基本流到三维工业和环境应用的各种情况下的雷诺平均纳维尔-斯托克斯（RANS）闭包的层次结构。一般的二阶矩封闭被简化为线性涡粘性模型，演示了如何评估更简单的方案的适用性和条件下，他们给出满意的预测。第二版的主要变化反映了计算能力的影响：一个新的章节致力于非定常RANS和另一个关于如何大涡模拟，LES和RANS策略可以有效地结合起来，用于特定的应用。这本书将仍然是标准的那些在工业界和学术界寻求专家指导的建模选项，并为研究生在物理学，应用数学和工程进入世界的湍流计算流体动力学。
Modelling transport and mixing by turbulence in complex flows are huge challenges for computational fluid dynamics (CFD). This highly readable book introduces readers to modelling levels that respect the physical complexity of turbulent flows. It examines the hierarchy of Reynolds-averaged Navier-Stokes (RANS) closures in various situations ranging from fundamental flows to three-dimensional industrial and environmental applications. The general second-moment closure is simplified to linear eddy-viscosity models, demonstrating how to assess the applicability of simpler schemes and the conditions under which they give satisfactory predictions. The principal changes for the second edition reflect the impact of computing power: a new chapter devoted to unsteady RANS and another on how large-eddy simulation, LES, and RANS strategies can be effectively combined for particular applications. This book will remain the standard for those in industry and academia seeking expert guidance on the modelling options available, and for graduate students in physics, applied mathematics and engineering entering the world of turbulent flow CFD.
