Beschreibung
This book highlights by careful documentation of developments what led to tracking the growth of deterministic disturbances inside the shear layer from receptivity to fully developed turbulent flow stages. Associated theoretical and numerical developments are addressed from basic level so that an uninitiated reader can also follow the materials which lead to the solution of a long-standing problem. Solving Navier-Stokes equation by direct numerical simulation (DNS) from the first principle has been considered as one of the most challenging problems of understanding what causes transition to turbulence. Therefore, this book is a very useful addition to advanced CFD and advanced fluid mechanics courses.
Covers the topic of DNS from first principles, while relating this to the canonical problem of transition over zero pressure gradient boundary layer
Emphasizes the new subject of boundary layer receptivity over the classical topic of instability approach
Identifies spatio-temporal wave fronts to explain fluid flow phenomenon of transition that is unique and very revealing on the mechanism of transition
