Overview

This course builds upon students鈥 understanding of thermofluids to enable the design of efficient combustion systems. The properties of renewable fuels are different to fossil fuels, so characterisation of their behaviour in combustion systems is necessary to successfully transition from fossil fuels, by reducing pollution and the effects of greenhouse gasses.

This course will provide an overview of the nature of combustion, including the chemical reactions which drive the heat release from the fuel and air (the "reactants") and the fluid mechanics which enable the reactants to interact with the ignition source. Students will analyse how reactants are converted to products in the various types of combustion engines and furnaces. They will then investigate the special natures of liquid and solid fuels. Advanced content will include the application of the knowledge obtained to model or simulate real combustion systems. Students who have also completed MEC5100 Computational Fluid Dynamics will have the opportunity to perform more detailed and accurate simulations.

Course learning outcomes

On successful completion of this course students should be able to:

  1. Analyse combustion chemistry and fundamental flow problems;
  2. Evaluate premixed and non-premixed combustion processes within the context of internal combustion engines and furnaces;
  3. Evaluate liquid fuels and their behaviour in combustion systems to enable the classification of the fuel;
  4. Evaluate the complex pathways of solid fuel combustion;
  5. Generate a model or simulation of real combustion systems;
  6. Critically evaluate the efficiency of combustion systems and the consequential socio-economic and environmental impacts.
