Fluid Mechanics

Fluid Mechanics
Objectives
Generate an awareness of the ubiquity of Fluid Mechanics in the “real world”
Apply fundamental knowledge of Fluid Mechanics to engineering challenges
Promote and practise skills in collecting, sifting, understanding and summarising information
Develop written and diagrammatic presentation skills
Exercise
The outcome of this assignment is a report that addresses the questions raised in the topic description.
Informed by the objectives detailed above, the assignment involves the following:
The final part of the exercise requires the preparation of a cogent report that integrates the information
gathered and its synthesis.
Report
Each student must submit a single report of 3 pages (including all the sections)
The report must be prepared using the template provided on BlackBoard and must include the following
sections:
Header: Provide the following details in the sequence: Name, student ID, date of the report and topic title.
Introduction: This section of maximum half a page should provide some context for the topic chosen and
highlight the different aspects described in the main body.
Main body: This contains the description or synthesis of the knowledge sourced in a logical form so that the
reader can easily assimilate the findings of the investigation.
Sections and subsections (both
unnumbered) should be included to make the presentation clearer. Equations, figures and tables
should be included in the main body where appropriate and cited in the text by their number.
Conclusion: This section provides a set of brief conclusions which encapsulate the findings of the
investigation.
References: This section lists all the sources of information (no more than 10) that contributed to the report.

List of Topics
Choose one
1. High-speed flight
Air is compressible at high flow speeds and the Bernoulli equation certainly does not hold at supersonic
speeds. Wings on conventional subsonic aircraft are very different to those used for supersonic aircraft
and this suggest a different mechanism for lift generation. Investigate how aircraft wings generate lift at
supersonic speeds and how this mechanism influences the design of wings suitable for supersonic
aircraft.
2.
Active flow control
Flow control aims to manipulate the flow (boundary layer, separation, etc) around vehicles to reduce
their drag and increase their lift, for instance. Investigate and describe advanced techniques based on
actuators requiring energy (e.g. suction or blowing, synthetic jets, etc) used to control the flow around
vehicles such as cars and aircrafts.
3.
Slurry flows in the resource industries in the mining industry, which is a very important contributor to
WA’s revenue, many of the fluids are slurries comprising a mixture of suspended particles in a liquid. The
behaviour of this Non-Newtonian mix differs radically from that of conventional Newtonian fluids.
Investigate the topic of Non-Newtonian fluids and describe how they can be modelled. Also describe the
challenges, and how they have been overcome, in dealing with these fluids, for example in pump design
and moving them through pipes.
4.
Underwater motion using supercavitation
The acceleration of the water around submerged objects moving at high speeds can lead to a drop in
pressure below the vapour pressure and to the formation of vapour bubbles. This phenomenon called
cavitation can be used to reduce skin-friction drag on high-speed underwater vessels. Investigate and
explain how supercavitation is used for the design of underwater devices and ships.
5.
Fluid Mechanics in Renewable Energy
Fluid Mechanics is an essential feature of nearly all forms of renewable energy. Investigate examples of
renewable-energy generation and explain the fluid principles at work in each.
6.
Underground mine ventilation
Efficient ventilation is critical for workers and equipment operating in underground mines. Its main
purposes are the supply of fresh air and the extraction of potentially toxic gases, dust and heat.
Investigate and describe designs of ventilation systems and the factors affecting gas flows in
underground tunnels.
7.
Animal motion
It is advantageous for animals to experience low drag when they swim or fly because, for the same
energy expenditure, they can move faster or keep moving for longer. Using examples, investigate and
describe the ways that animals have evolved so that their drag has become lower.
