The study of fluid dynamics is one of the fundamental disciplines in Mechanical Engineering. In the first part of the course, students will learn about boundary-layer theory, which is a key element of aerodynamic design. Students will also learn about the atmospheric boundary layer and learn how this affects the design of cities, meteorological forecasts and pollutant dispersion. A guest-lecture series on wind engineering will build on this knowledge to give students a perspective on one of the most important forms of renewable energy in our society today.

In the second part of the course, students will learn about data acquisition and analysis. These skills are required of engineers working with the technology of today and into the future. The course will help students understand the costs, difficulties and possibilities afforded by sensor systems and instrumentation, with applications for, but not limited to, fluid dynamics.

INDICATIVE CONTENT

This subject will cover selected advanced topics in fluid mechanics. Building on previous fluids courses, the subject is broadly split into two units, although content of these will overlap.

Unit 1: Turbulence and boundary layers. Topics covered include Navier-stokes equations applied to wall-bounded flows, similarity solutions of the boundary layer equations, Blasius solution, Falkner and Skan solution, separated flows, turbulent boundary layers, Reynolds averaged Navier-Stokes equations, scaling parameters, pipe friction, Von Karman momentum integral equation, atmospheric turbulence.

Unit 2: Experimental techniques. Through a series of lectures, labs and assignments, students will be introduced to key concepts of experimental (and numerical) techniques related to experiments in fluid mechanics. Topics will include: data analysis (to include correlations, fast Fourier transform, energy spectra); Particle Image Velocimetry (PIV); hot-wire anemometry; advanced potential flow numerical techniques.

INTENDED LEARNING OUTCOMES / SUBJECT OBJECTIVES

At the conclusion of this subject the student is expected to -

1 - Understand the limitations and advantages of various experimental techniques for fluid mechanics, and also have a sound understanding of the physics underpinning these techniques
2 - Apply contemporary data analysis techniques for experiments in the area of fluid mechanics, especially for experiments relating to boundary layers and turbulence
3 - Apply the techniques of particle image velocimetry and hot-wire anemometry to investigate complex fluid flows
4 - Understand how the equations of fluid motion are applied to flows near walls
5 - Understand the importance of the boundary layer in engineering applications
6 - Understand the role of turbulence in the atmosphere including weather prediction

One 2 hour examination (40%) at the end of semester. Associated with Intended Learning Outcomes (ILOs) 4-6.

Five assignments (including laboratory reports) during semester worth a total of 60%. These assignments will be a combination of laboratory work, computational work and advanced data analysis. Assignments will all involve basic programming skills (for data treatment and analysis). Associated with ILOs 1-3.

INDICATIVE ASSESSMENT INFORMATION

Two 2 hour laboratory classes will be followed with reports for assessment. Each report should not exceed 1500 words. The reports are submitted in groups.

Three written assignments assessed as a combination of individual and group assignments. Each will consist of no more than 1000 words.

This subject is not available as a breadth subject.

On completion of this unit a student is expected to have the skills to -

• Apply knowledge of science and engineering fundamentals
• Undertake problem identification, formulation, and solution
• Be proficient in engineering design
• Communicate effectively with the engineering team and with the community at large
• Be creative and innovative

LEARNING AND TEACHING METHODS

The subject will be delivered through a combination of lectures, guest lectures, tutorials and laboratory demonstrations. The laboratory classes and tutorials are highly interactive and computer software will be used during lectures and laboratory classes.
