The course develops incompressible and compressible flow topics of broad interest to mechanical engineers. It demonstrates the link between well-developed theoretical studies and their practical application in offshore technology, aeronautics, engine design and fluid machinery. The course begins with water wave theory with particular application to coastal and offshore engineering. This is followed by consideration of boundary layer development over a flat plate and curved surfaces, leading to boundary layer separation and forces on immersed bodies. These topics are also part of the EA40JF Civil Engineering Hydraulics course. The second part of the course concentrates on compressible flow. Using the fundamental conservation equations, the characteristics of converging-diverging nozzles and accelerating supersonic flows are examined. Plane and oblique shock waves, Prandt-Meyer flow and Navier-Stokes equations are then introduced. The course concludes with a discussion of the behaviour of transonic aerofoils, and the design of supersonic engine inlets.
