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.
