Unit Description and General Aims
The objective in presenting this unit is to provide students with detailed knowledge of the principles and practices governing the field of fluid mechanics.
The unit will include: basic fluid properties and laws governing fluid statics; principal concepts and methods of fluid kinematics and dynamics; fluid system flow analysis utilising the Continuity, Bernoulli, and Momentum equations; flow system analysis including boundary layer concepts and modelling based on dimensional analysis. Students will also undertake a project work involving modelling (for example, computational fluid dynamics).
At the conclusion of this unit, students will have been imparted with the requisite knowledge to comprehend, distinguish, and apply the principles and practices governing the field of fluid mechanics in their future work.
