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.

Kemal Hanjalić is Professor Emeritus at Delft University of Technology and an international fellow of the UK's Royal Academy of Engineering and the Russian Academy of Science. His innovative and sustained contributions to turbulence-model development, including heat transfer and environmental flows have been recognised by the Max Planck and Nusselt-Reynolds Research Prizes. Brian Launder, Emeritus Professor at the University of Manchester, has enjoyed more than a half-century of turbulence-modelling projects with his co-author. Widely cited for his two-equation eddy-viscosity modelling, his main focus has been stress-transport and non-linear eddy-viscosity closures. He was elected FRS and FREng for his turbulence research with honorary doctorates from three European universities.

Review of previous edition: 'The authors have been top researchers in the field for over 40 years, and have collaborated many times, so their writing is seamless. Their passion, maturity, clarity, lucidity, and intellectual honesty are impressive in a field which has had its fair share of wild claims or simply near-delusions. This is a permanent, detailed, authoritative and inspiring reference in a field of engineering science which will be very challenging, active and important for years to come.' Philippe Spalart, SIAM Review
