Doyle Knight – författare

Rapid advances in Direct Numerical Simulation (DNS) and Large Eddy Simulation (LES) of turbulence provide opportunities for improved prediction of incompressible and compressible turbulent flows. The book includes five invited and thirty-eight contributed papers presented at the Second AFOSR International Conference on DNS and LES held at Rutgers - The State University of New Jersey, on June 7-9, 1999. A broad range of topics in DNS and LES are presented, including new developments in LES modeling, numerical algorithms for LES and DNS, DNS and LES of reacting flows, and DNS and LES for supersonic and hypersonic boundary layers. The book provides a extensive view of the state of the art in DNS and LES.

The book presents a comprehensive summary of experiments and high-fidelity simulations (using Direct Numerical Simulation [DNS] and Large Eddy Simulation [LES]) of rough wall pipe and channel flows, and turbulent boundary layers from subsonic to hypersonic speeds. Although the field of rough wall turbulent boundary layers and rough wall turbulent pipe flow has been studied for nearly 200 years, there is no comprehensive summary of the experiments and high-fidelity simulations (LES and DNS) incorporating example results for each investigation. Dr. Knight further provides background information on turbulent boundary layers and pipe flow, together with a brief introduction to Direct Numerical Simulation and Large Eddy Simulation. A summary chapter describes the knowledge of the roughness function, examines the validity of Townsend’s similarity hypothesis and details the available data of experimental and high-fidelity simulation turbulence statistics and understanding of the rough wall turbulence structure, illustrating the importance of the phenomena in aerodynamics, aerospace, and civil, environmental, and mechanical engineering.Shows the connection to aerodynamic drag on wings; efficiency of propellors, and pollutant dispersion in urban areasExamines high fidelity simulations (LES and DNS) of rough wall turbulent boundary layers, pipe, and channel flowsSummarizes over 100 years of experimental results for rough wall turbulent boundary layers and rough wall pipe flow
