Thesis:
Reason for project:
Most quadcopters are currently powered by LiPo batteries. In many applications this results in limited flight time. Fuel cells have been proven to increase the flight time two- to threefold. This hasn’t been done yet in the southern hemisphere. There is, therefore, a desire to develop fuel cell powered propulsion systems for quadcopters.

Deliverable of project:
A fuel cell has a higher energy density than a LiPo battery. However, it has a lower power density and more complex characteristics. The design process of a fuel cell propulsion system, is therefore more complex. Also, propulsion systems are generally custom designed for specific missions/applications. There is, therefore, a need to develop a computer simulation design tool that could simplify the design process of fuel cell propulsion systems. The aim of this project is to develop, validate and demonstrate the usefulness of such a design tool.

Competencies developed during this project:

  • Theoretically modelling a fuel cell, LiPo battery, ESC, BLDC, propeller and other components using Matlab/Simulink/Simscape
  • Liaising with manufacture to procure a custom-designed multirotor
  • Designing experiments, procuring test equipment, doing experiments and analysing data

[Refer to references 1 & 2.]

Subjects:
Solar Thermal Energy Systems: learnt how to simulate and design Concentrated Solar Powered (CSP) systems.
Advanced Design: Learnt how to program optimization algorithms and how to solve optimization problems.
Industrial Heat exchangers: Learnt how to analyze and design heat exchanger systems, focusing on cooling towers for power stations.
Advanced Control Systems: learnt about implementing multi-input-multi-output control.
Numerical Methods: Learnt how to efficiently solve large matrix problems.

Head tutor:
At our university, for each subject, a handful of postgraduate students help the undergraduate students with their tutorials and practicals. I was the head tutor, which meant I coordinated the efforts of the tutors. This subject comprises of thermodynamics, fluid dynamics and heat transfer. I gained a more in-depth understanding of these fields by teaching it.

Final year project:

Reason for project:
My supervisor developed a furnace to heat water. The way this furnace was set-up, it required an induced-draught fan that could deliver a high pressure and handle high temperatures. Such a fan couldn’t be found as a COTS product. It, therefore, needed to be developed.

Deliverables of project:
The object of this project was to design, build, test and install a fan to meet the above-mentioned characteristics (high pressure and temperature).

Competencies developed during this project:

  • Theoretical modelling of a fluid dynamics system, and theoretical turbomachinery design
  • Detailed CAD design using Inventor Professional
  • Managing manufacturing process:
    • Outsourcing laser-cutting of parts (approximately 20 unique parts)
    • Communicating and supervising welding of subsystems
    • Assembling of subsystems, myself
  • Designing and building test setup, doing experiments and analysing data
