Direct Numerical Simulation and Multiscale Modelling For Turbulence, Combustion and Multiphysics

Direct Numerical Simulation and Multiscale Modelling provides a unified description of DNS, LES and RANS in the context of broader modelling and simulation practice. The relevance of these techniques to flow, turbulence, combustion and multiphysics is explained to help readers apply them to a wide range of research topics.

Introductory sections help readers get up to speed with the theories of turbulence, combustion, and multiphysics, along with the basics of simulation and modelling. This is followed by thorough treatments of the numerical methods, boundary conditions, and specific modelling approaches for different purposes. Applications in fields including aerospace, biomedical, and chemical engineering are investigated where appropriate.

This is the ideal guide for readers interested in direct numerical simulation, or modelling/simulation of turbulence more generally, who need an overview of the methods available and advice on how to select and implement the correct one.

• Includes an appendix listing useful websites with downloadable codes and video clips
• Addresses DNS and LES for both incompressible and compressible flow
• Provides an overview of current challenges, emerging research directions, and possible future developments in the field

Professor Luo holds the Chair of Energy Systems in the Department of Mechanical Engineering at UCL. He has more than 30 years' research and teaching experience in advanced numerical simulations as applied to flow, turbulence and combustion in aerospace, energy and propulsion technologies as well as multi-physics problems in interdisciplinary sciences. He was among the earliest researchers in the world to have worked on Direct Numerical Simulation (DNS) and Large Eddy Simulation (LES). He obtained a PhD (1992) from Cambridge University Engineering Department under the supervision of Professor K. N. C. Bray, FRS, a leading combustion theoretician and subsequently (1991 - 1993), worked as a postdoctoral research associate at Imperial College London, with Professor David Gosman, FREng, one of the pioneers in Computational Fluid Dynamics (CFD). He then worked with Professor Neil Sandham at Queen Mary, University of London on DNS of compressible flow before becoming a lecturer there in 1995. He was promoted to Chair of Computational Fluids and Combustion in 2002. He subsequently took up the Chair of Energy Systems in the University of Southampton, where he led a large multidisciplinary team working on both conventional and renewable energy technologies during 2004-2013. He took his current position at UCL in 2013.

Currently, he is leading the "UK Consortium On Mesoscale Engineering Sciences (UKCOMES) . For his pioneering and outstanding work on DNS of turbulent combustion, he received the Sugden Award and the Gaydon Prize from the Combustion Institute British Section. He has published over 300 papers in international journals, conferences and books. He is an elected Fellow of IMechE, IoP and ASME and an Associate Fellow of AIAA.
