Vocabulary of Mechanics, Volume 2: Group 15. Mechanics of Fluids provides information pertinent to the fundamental aspects of the mechanics of fluids. This book covers a variety of topics, including fluid mechanics, hydrostatics, aeromechanics, gas dynamics, aeroelasticity, and dynamic meteorology. Organized into two parts encompassing 95 sections, this volume begins with an overview of the branch of mechanics dealing with the phenomena of fluids in motion and at rest. This text then deals with the geometrical description of the flow of matter, irrespectively of the forces producing the motion. Other sections consider the instantaneous motion of a fluid element wherein the motion is composed of translation of the center of mass of a fluid element. This book discusses as well the relative equilibrium of liquids. The final section deals with the atmospheric air motion caused by several factors. This book is a valuable resource for engineers, scientists, and research workers.
This is an introductory fluid mechanics text, intended for the first Fluid Mechanics course required of all engineers. The goal of this book is to modernise the teaching of fluid mechanics by encouraging students to visualise and simulate flow processes. The book also introduces students to the capabilities of computational fluid dynamics (CFD) techniques, the most important new approach to the study of fluids. Fluid mechanics is traditionally one of the most difficult topics in the curriculum for ME students: this text aims to overcome those learning difficulties through visualisation of the key concepts.Contents: 1.

This book provides readers with the most current, accurate, and practical fluid mechanics related applications that the practicing BS level engineer needs today in the chemical and related industries, in addition to a fundamental understanding of these applications based upon sound fundamental basic scientific principles. The emphasis remains on problem solving, and the new edition includes many more examples.
Suitable for both a first or second course in fluid mechanics at the graduate or advanced undergraduate level, this book presents the study of how fluids behave and interact under various forces and in various applied situations - whether in the liquid or gaseous state or both.
This is a collection of problems and solutions in fluid mechanics for students of all engineering disciplines. The text is intended to support undergraduate courses and be useful to academic tutors in supervising design projects.
Fluid mechanics is the study of fluids including liquids, gases and plasmas and the forces acting on them. Its study is critical in predicting rainfall, ocean currents, reducing drag on cars and aeroplanes, and design of engines. The subject is also interesting from a mathematical perspective due to the nonlinear nature of its equations. For example, the topic of turbulence has been a subject of interest to both mathematicians and engineers: to the former because of its mathematically complex nature and to the latter group because of its ubiquitous presence in real-life applications. This book is a follow-up to the first volume and discusses the concepts of fluid mechanics in detail. The book gives an in-depth summary of the governing equations and their engineering related applications. It also comprehensively discusses the fundamental theories related to kinematics and governing equations, hydrostatics, surface waves and ideal fluid flow, followed by their applications.
