Overview
Mechanical engineers are expected to have the knowledge and the understanding of the basic principles and concepts of fluid mechanics both in static and dynamic conditions. This is to enable them to analyse and design systems in which fluid is the working medium.
This course presents the fundamental concepts of fluid behaviour both under static and dynamic conditions. This course is designed to enable the student to analyse and design any practical systems in which fluid is the working medium. The content of this course includes statics and dynamics of fluid flow, dimensional analysis, internal viscous flow (eg laminar and turbulent flows in pipes and ducts), viscous flow around bodies, boundary layer and compressible flow.
Course learning outcomes
The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:
- estimate the forces on submerged bodies in static fluid situation;
- analyse the transportation of different types of fluids in a variety of applications and be able to avoid unwanted phenomena such as cavitation and water hammer;
- estimate the forces on moving, or stationary bodies caused by flowing fluids, either internally or externally such as forces on nozzles, elbows, blades and drag forces on chimneys, high rise buildings, different types of constructions, aircraft and ships;
- analyse the behaviour of high-speed flows i.e. compressible flow in ducts, nozzles and diffusers.
