Beskrivning

The discovery of coherent structures in turbulent shear flows and the model developments in computer capabilities have revolutionized research work in turbulence. Interest in nonlinear stability waves has increased for understanding the later stages of the laminar-turbulent transition process and understanding the physics of coherent structures. In addition, advances in computers have made direct numerical simulation possible at low-Reynolds numbers and large-eddy simulation possible at high-Reynolds numbers, which facilitates prediction of turbulence-generated noise. "Transition, Turbulence, and Noise" aims to provide a graduate-level introductory study of turbulence while accounting for such recent developments in transition and turbulence research. The theoretical basis presented is sufficient for studying specialized literature on turbulence and for theoretical investigation on the subject. This book should be of interest to both research engineers and graduate students in science and engineering.
