Modelling Turbulence in Engineering and the Environment
Modelling Turbulence in Engineering and the Environment
Brian Launder, University of Manchester
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.
- Updated for the second edition, with new material exploring hybrid approaches that involve a time-dependent resolution of the flow
- Helps the CFD user find the model that best suits their professional needs
- Includes extensive examples ranging from fundamental homogeneous flows to three-dimensional industrial and environmental applications
Reviews & endorsements
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.'
