Fluid Mechanics: An Intermediate Approach helps readers develop a physics-based understanding of complex flows and mathematically model them with accurate boundary conditions for numerical predictions. The new edition starts with a chapter reviewing key undergraduate concepts in fluid mechanics and thermodynamics, introducing the generalized conservation equation for differential and integral analyses. It concludes with a self-study chapter on computational fluid dynamics of turbulent flows, including physics-based postprocessing of 3D CFD results and entropy map generation for accurate interpretation and design applications. The book includes numerous worked examples and end-of-chapter problems for student practice. It also discusses how to numerically model compressible flow over all Mach numbers in a variable-area duct, accounting for friction, heat transfer, rotation, internal choking, and normal shock formation. The book is intended for graduate mechanical and aerospace engineering students taking courses in Fluid Mechanics and Gas Dynamics. Instructors will be able to utilize a Solutions Manual for their course. The eBook+ version of the book includes the following enhancements: Pop-up key words: Hovering over a highlighted word will reveal the definition in a pop-up bubble. Video lectures: Chapters 1 and 6 feature video presentations to enhance understanding of key concepts and can be played, paused, and rewound using the integrated controls. Flash cards: Interactive flashcards at the end of each chapter can be used to review key terms; hovering over the flashcard will display the term’s definition. Multiple-choice quizzes: Each chapter includes several multiple-choice questions to help readers reinforce their understanding of the content. Open-ended questions: Open-ended questions at the end of each chapter include a link to a pop-up view of a sample answer.
