Fluid mechanics 2

The foundations of continuum analysis of fluids will be presented. Using control volume analysis the fundamental conservation laws for mass, momentum and energy are developed leading to the derivation of the Navier-Stokes equations. Techniques employed to solving these equations for specific problems are explored. Methods of exact and approximate solutions of these equations, and the use of conceptual and analytical tools such as flow similitude, vorticity, circulation, stream function and velocity potential are described. The concept of boundary layers and its use in the calculation of drag and lift forces is elucidated. The origins and physical consequences of the phenomenon of fluid turbulence are discussed, along with their implications for computation of turbulent flows. The analysis of compressible flows and its applications are discussed. The unit introduces the concepts underpinning the broad areas of fluid acoustics, computational fluid dynamics, environmental fluid mechanics and wind energy.
