Rough Boundary Layer, Friction, and Drag

Description

Rough Boundary Layer, Friction, and Drag is about subtle surface roughening, surface texturing, primarily for drag reduction. In recent years, this surface texturing has been making significant inroads in aerodynamic performance improvement, heat convection augmentation, and many other engineering applications. These advancements are made possible via careful observation followed by detailed imitation of a wealth of amazing intelligent designs in nature. This introductory text aims at inspiring inquisitive minds to recognize and appreciate this innovative engineering. The underlying flow physics and mechanisms involved in handsome friction reduction are elucidated with the help of simple, illustrative figures. Basic undergraduate background in fluid mechanics would facilitate the comprehension of the covered material.
