Fundamentals of Aerodynamics

John D. Anderson Jr.

A comprehensive introduction to aerodynamic theory, from basic flow concepts through incompressible and compressible applications. Anderson connects conservation laws and fluid mechanics with airfoil, wing, and aircraft analysis. It suits upper-level aerospace and mechanical engineering students with prior calculus and fluid mechanics.

Prerequisites: A first course in fluid mechanics, multivariable calculus, and ordinary differential equations; introductory thermodynamics for the compressible-flow chapters.

Chapter Summary

The book has twenty chapters in four parts. The publisher describes it as a text "for students", written in a clear, informal and direct style that speaks to the reader. The parts run from general principles, through inviscid incompressible flow and inviscid compressible flow, to viscous flow.

Part One, Chapters 1–2: Aerodynamics: Some Introductory Thoughts; Aerodynamics: Some Fundamental Principles and Equations

The first chapter introduces the subject, and the second sets out the principles and equations on which the rest of the book depends. Later chapters build on this pair, so it is the place to settle the governing equations.

Part Two, Chapters 3–6: Inviscid, Incompressible Flow

Chapter 3, Fundamentals of Inviscid, Incompressible Flow, develops the basic theory. Chapter 4, Incompressible Flow over Airfoils, and Chapter 5, Incompressible Flow over Finite Wings, apply it to the two main lifting surfaces. Chapter 6, Three-Dimensional Incompressible Flow, follows the two applied chapters.

Part Three, Chapters 7–14: Inviscid, Compressible Flow

This is the longest part. Chapter 7, Compressible Flow: Some Preliminary Aspects, opens it, followed by Chapter 8, Normal Shock Waves and Related Topics, and Chapter 9, Oblique Shock and Expansion Waves. Chapter 10 covers Compressible Flow Through Nozzles, Diffusers, and Wind Tunnels. Chapter 11, Subsonic Compressible Flow over Airfoils: Linear Theory, and Chapter 12, Linearized Supersonic Flow, give the linearized theories for the two speed regimes. Chapter 13, Introduction to Numerical Techniques for Nonlinear Supersonic Flow, turns to numerical methods, and Chapter 14, Elements of Hypersonic Flow, closes the part.

Part Four, Chapters 15–20: Viscous Flow

Chapter 15, Introduction to the Fundamental Principles and Equations of Viscous Flow, starts the part, and Chapter 16, A Special Case: Couette Flow, treats one exactly solvable case. Chapter 17, Introduction to Boundary Layers, leads into Chapter 18, Laminar Boundary Layers, and Chapter 19, Turbulent Boundary Layers. Chapter 20, Navier-Stokes Solutions: Some Examples, ends the book.

Key Concepts

Part One: Principles (Chapters 1–2)

  • Fundamental principles and equations: the governing relations of aerodynamics that every later chapter applies.

Part Two: Incompressible Flow (Chapters 3–6)

  • Inviscid, incompressible flow: the idealised flow model used for airfoil and wing theory at low speed.
  • Airfoils and finite wings: the two lifting-surface problems treated in Chapters 4 and 5.
  • Three-dimensional flow: flow past bodies where a two-dimensional model is not enough.

Part Three: Compressible Flow (Chapters 7–14)

  • Normal shock waves: abrupt changes of flow properties across a shock perpendicular to the flow.
  • Oblique shocks and expansion waves: the corresponding supersonic turning-flow phenomena.
  • Nozzles, diffusers and wind tunnels: internal compressible flow in ducts of varying area.
  • Linearized theory: small-disturbance treatments of subsonic and supersonic flow over airfoils.
  • Hypersonic flow: the high-Mach-number regime introduced in Chapter 14.

Part Four: Viscous Flow (Chapters 15–20)

  • Couette flow: a simple viscous flow used as a first exact case.
  • Laminar and turbulent boundary layers: the thin viscous layers next to a surface, treated in separate chapters.
  • Navier-Stokes solutions: worked examples of the full viscous equations.

Critical Analysis

Strengths

  • A complete arc from low speed to hypersonic and viscous flow. The four parts take a reader through incompressible, compressible and viscous aerodynamics in one book, with the same author and notation throughout.
  • Written for the learner. The publisher stresses a clear, informal and direct style aimed at students, and presents the book as one to be read and understood rather than only consulted.
  • Compressible flow gets sustained attention. Eight of the twenty chapters cover inviscid compressible flow, from shocks and nozzles to linearized and hypersonic flow, a large share of the book for readers who need high-speed flow.
  • A structure that allows selection. The division into four parts lets an instructor or self-studier follow the incompressible path first and add compressible or viscous flow as the course requires.

Limitations

  • Length and breadth. With twenty chapters, the book contains more than a single course normally covers, and the reader has to choose a route.
  • Assumes prior fluid mechanics. The book begins with aerodynamic principles rather than basic fluid statics or properties, so it works best after an introductory fluid mechanics course.
  • Computation is limited to introductions. Numerical techniques appear in Chapter 13 for supersonic flow, and Chapter 20 gives selected Navier-Stokes solutions; a reader who needs computational fluid dynamics will need a specialist text.

Where It Fits in the Course

In this fluid mechanics course, Anderson is the specialist aerodynamics text. Young, Munson and Okiishi's A Brief Introduction to Fluid Mechanics is an accessible introduction to fluid statics, conservation laws and flow analysis, and Nakayama's Introduction to Fluid Mechanics explains the same basics with the help of flow photographs. Lauga's Fluid Mechanics: A Very Short Introduction is a non-technical overview. Any of these prepares for Anderson.

White and Xue's Fluid Mechanics is a comprehensive engineering text that also covers boundary-layer, potential and compressible flow, so it is the natural general companion for the viscous and compressible parts. Kundu, Cohen, Dowling and Capecelatro's Fluid Mechanics is a graduate-level treatment of the governing equations and can follow Anderson's Parts Two and Four for readers who want more theory. Anderson narrows to wings, shocks, boundary layers and high-speed flow rather than the whole of fluid mechanics.

How to Use This Book

The book is for aerospace and mechanical engineering students taking a dedicated aerodynamics course. Prior study of calculus, differential equations and an introductory fluid mechanics course is expected; thermodynamics helps for the compressible chapters.

A practical plan for a first aerodynamics course:

  • Core: Chapters 1–5. They establish the principles and the incompressible theory of airfoils and finite wings.
  • Compressible flow: Chapters 7–10 for shocks, expansion waves and nozzle flow; Chapters 11–12 if the course reaches airfoil theory at high speed.
  • Viscous flow: Chapters 15, 17 and 18 give an introduction to the Navier-Stokes equations and laminar boundary layers; Chapter 19 follows for turbulent boundary layers.
  • Optional: Chapter 6, Chapter 13, Chapter 14, Chapter 16 and Chapter 20, depending on whether the course emphasises three-dimensional flow, numerical methods, hypersonics or exact viscous solutions.

Work the incompressible chapters carefully before moving on, since the compressible chapters reuse the same conservation-law reasoning. Keep a general fluid mechanics text at hand for background on fluid properties and control volumes.
