The study of the movement of liquids and gases is known as fluid dynamics. This book on fluid dynamics deals with the applied and computational methods of fluid dynamics. This field follows the basic laws of motion and force to measure and predict the various flows that occur to a body, either at motion or rest. Fluid dynamics is applied to a wide variety of fields such as hydrology, limnology, aeronautics, astronomy, etc. This book is a compilation of chapters that discuss the most vital concepts and emerging trends of this field. It is meant for students who are looking for an elaborate reference text on fluid dynamics. This text is a complete source of knowledge on the present status of this important field.
