Fluid Mechanics

Presenting the kinematics and governing equations for Newtonian fluid, this book shows how suitable approximation can help solve problems of practical importance. Various approximations such as ideal fluid flow model, boundary layer theory, the acoustic approximation, and so on, are derived. In its discussion of compressible fluids, this book deviates from the practice of using gas tables, and presents an approach more amenable to solution using computers. The control volume and the differential equation forms of governing equations are dealt with in detail, and the advantages and shortcomings of each approach are discussed by means of examples. The implications of frame-indifference and the laws of thermodynamics are also discussed in detail. Numerous examples are presented to illustrate the theory at each stage of the development. For those interested more in the applications than in the theoretical aspects of fluid mechanics, a detailed summary of the relevant equations has been presented at the outset.
