Description
Book SynopsisDrag reduction is a field of study in many engineering disciplines, and its aim is to reduce the fluid-mechanical forces exerted in an object in order to improve its mechanical and/or fuel efficiency. This book provides a guide to the current state-of-the-art in this area of engineering.
