This book presents a focused, readable account of the principal physical and mathematical ideas related to different physical geometries at the aspects of fluid dynamics. Researchers in engineering, applied math, and physics who are taking their interest in fluids will find this book invaluable in providing the background in physics and mathematics necessary to pursue advanced research. The book includes a detailed many applications of the Navier-Stokes and energy equations, followed by many examples of their use in studying the dynamics of fluid flows through advanced models. Many applications are designed with a view toward using computer programming or its equivalent to simplify and extend the analysis of fluid motion including developing flow simulations based on numerical techniques described in the book.
