دانلود کتاب Introduction to Fluid Mechanics

Introduction to Fluid Mechanics provides a balanced and uniquely visual treatment of the tools used in solving modern fluid mechanics problems. Presenting an image-intensive approach to fluid dynamics through classic kinematic concepts, the book demonstrates the importance of flow visualization in a framework of modern experimental techniques and flow simulation.Detailed photographs and diagrams of fluid motions and phenomena throughout the text help students to see and understand why equations change drastically for different types of flows. Output illustrations from CFD (computational fluid dynamics) programs illustrate the possibilities of flow behavior, enabling students to concentrate on ideas instead of mathematics. The book also provides the means to solve interesting problems early in the course by presenting case studies at the beginning of the text. These cases are revisited later to reinforce empirical rules and help explain advanced methods of analyzing a flow.Creating a foundation for further study in this important and exciting field, Introduction to Fluid Mechanics is ideal for a first course in fluid mechanics. The book is designed to accommodate students concentrating in mechanical engineering as well as those in the civil, aerospace, and chemical engineering fields.-Книга предлагает сбалансированную и уникальную визуальную демонстрацию инструментов, используемых в решении современных задач механики жидкостей. Предлагая интенсивный визуально-ориентированный подход к гидрогазодинамике через классические кинематические понятия, демонстрируется важность визуализации потока в структуре современных экспериментальных методов и моделирования потока. Детальные фотографии и диаграммы движений жидкостей и явлений по тексту помогают студентам видеть и понять, почему уравнения изменяются решительно для различных типов потоков. Выходные данные программы CFD (вычислительная гидрогазодинамика) иллюстрируют возможности поведения потока, позволяя студентам сконцентрироваться на идеях вместо математики. Книга также представляет средства для решения интересных проблем на ранних стадиях, путем представления тематических исследований, в начале этого текста. Эти случаи повторно освещаются позже, чтобы укрепить эмпирические правила, и помогают объяснить передовые методы анализа потока. Создавая базу для дальнейшего исследования в этой важной и захватывающей области, книга идеальна для первого курса изучения механики жидкостей. Книга разработана предназначена для студентов, специализирующихся в машиностроении, а также в гражданской, космической, и химической инженерии.-Релиз группы
