Description

Momentum Transfer in Fluids provides information pertinent to fluid mechanics. This book discusses several topics related to the movement of fluids, including boundary-layer analysis, statistical treatment of turbulence, as well as laminar and turbulent shear-flow.
Comprised of seven chapters, this book starts with an overview of the physical nature of momentum and describes the application of this concept to systems of variable weight, which are useful in the prediction of the physical behavior of fluids in motion. This text then explores the fundamental properties and the macroscopic aspects of turbulent flow. Other chapters present the significance and utility of mixing length and other macroscopic turbulence parameters. This book discusses as well the prediction of the velocity and friction as functions of position in the flowing stream. The final chapter deals with the qualitative aspects of boundary flows for compressible and incompressible fluids.
This book is a valuable resource for scientists and chemical engineers.
