Unit: MECH4241: Energy and the Environment (6 CP)
Mode: Normal-Day
On Offer: Yes
Level: Senior Advanced
Faculty/School: School of Aerospace, Mechanical & Mechatronic Engineering
Unit Coordinator/s: Professor Behnia, Masud
Session options: Semester 1
Versions for this Unit:
Campus: Camperdown/Darlington
Pre-Requisites: [24 credits of 3rd year units of study].
Brief Handbook Description: This unit is suitable for any engineering discipline student who is interested in developing an understanding of analysis and design in energy, power generation, environment and relevant economic issues. The aim is to acquaint students with the methods engineers use to design and evaluate the thermal processes used for the production of electricity. It also assesses and deals with the environmental consequences of power generation. At the end of this unit students will be able to carry out preliminary design and economic impact analyses for electrical power generation systems.

A series of topics will be covered in relation to energy and electricity and relevant issues. The course contents will include:

1. Economic analysis of energy systems;

2. Environmental impact of power generation;

3. Principles of thermodynamics;

4. First law analysis of power cycles;

5. Design and simulation of power generation cycles;

6. Second law efficiency and availability;

7. Energy efficiency;

8. CO2 capture and sequestration;

9. Design of various components of thermal power plants.
Assumed Knowledge: None.
