Advanced Viscous Fluid Flow is an in-depth guide to boundary-layer modelling strategies for fluid dynamicists. It starts by providing the strong theoretical background essential to understand laminar and turbulent boundary layers in a variety of multidimensional viscous problems for steady and unsteady motions, bounded by either hard or porous walls. Particular attention is given to viscous layers engendered in rotating and oscillating flows, especially those driven by wall-normal or wall-tangential injection. This is accomplished by covering incompressible laminar boundary layers, turbulent boundary layers, and free shear flows in multidimensional physical settings. Both differential and integral approaches are covered in detail with numerous illustrations and test cases based on recent developments in the field.This is intended as a graduate textbook on viscous motion with a well-balanced mix of engineering applications. It is also a valuable resource for those in academic or industrial research tackling boundary layers in complex, multidimensional problems.
