"The continuing goal of Viscous Fluid Flow, Third Edition is to serve as a senior or first-year graduate textbook on viscous flow with engineering applications. Students are expected to have knowledge of basic fluid mechanics, vector calculus, ordinary and partial differential equations and elementary numerical analysis. The material can be selectively presented in a one-semester course or, with fuller coverage, in two quarters or even two semesters." This book is primarily concerned with analysis and discussion of viscous flows. The field itself may be tending toward CFD and software applications. However, this text is meant to introduce viscous flows, including CFD, and to provide insight and concepts.
