An Introduction to Fluid Mechanics provides a balanced introduction for undergraduate engineers to all of the tools used for solving fluid mechanics problems today, and gives a foundation for further study of this important and exciting field. The book emphasises a visual presentation of fluid dynamics through classic kinematic concepts and demonstrates the importance of flow simulation. An additional feature of our coverage is that the student begins to appreciate the wealth of information available from skillful post-processing of CFD simulations. Simple, but effective, case studies on pipe flow, drag on spheres and cylinders, lift and drag on airfoils, and other topics introduce empirical results early in the text. The student learns more and more about the source of the empirical rules presented in the case studies as they are revisited throughout, showing the student how advanced methods contribute to a deeper understanding of a flow than can be gained from empirical methods alone. The final chapters cover common applications of fluid mechanics. It is here that students see how analytical, empirical, experimental and computational methods come together to solve engineering problems.
