The course begins with consideration of boundary layer development over a flat plate and curved surfaces, leading to boundary layer separation and forces on immersed bodies. This is followed by study of water wave theory with particular application to coastal and offshore engineering. These topics are also part of the EG40JF 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, Prandtl-Meyer flow and Navier-Stokes equations are then introduced.
