Fluid Dynamics-A Short Course

The book entitled Fluid Dynamics contains five chapters. This book is written for UG and PG students. Chapter 1 includes Real fluids and ideal fluids. Velocity of a fluid at a point. Stream lines and path lines. Steady and unsteady flows. Velocity potential. Velocity vector. Local and particle rate of change. Equation of continuity. Acceleration of a fluid. Condition at a rigid boundary. General analysis of fluid motion. Euler's equation of motion. Bernoulli's equation. Chapter 2 contains Sources, sinks and doublets. Images in a rigid infinite plane. Images in solid spheres. Axi-symmetric flows. Stokes' stream function.The theorem of Blausius. Chapter 3 contains The equations of state of a substance, the first law of thermodynamics, internal energy of a gas, functions of state, entropy, Maxwell's thermodynamic relation, Isothermal Adiabatic and Isentropic processes.
