AIMS

This subject forms one of the core units in the Masters of Energy Systems and the overall aims are to introduce the students to the tools and skills needed to analyze energy systems. To accomplish this overall aim, the subject introduces material and energy balances used in energy system calculations, and introduces and applies the Laws of Thermodynamics to simple energy systems.

This subject, together with ENGR90028 Introduction to Energy Systems, ENGR90030 Non-Renewable Energy, SCIE90014 Renewable Energy and ENGR90032 Energy Supply and Value Chains provide the core technical content for the Masters of Energy Systems.
The ability to analyze existing or new proposed energy systems is essential in assessing the merits and economics of our energy supply. This subject gives the students the opportunity to learn and apply these fundamental tools and skills with relevant and realistic energy systems.

INDICATIVE CONTENT

Topics include:

• thermodynamic properties
• equations of state
• the conservation of energy in and around energy processing systems
• evaluation of enthalpy changes with and without phase change
• simplified energy balances for batch, steady-state and adiabatic systems
• estimation of heats of combustion
• simultaneous material and energy balances
• entropy, the Second Law of Thermodynamics and Carnot’s principle
• simple thermodynamic cycles
• exercises in process optimisation and the solution of ill-defined process problems

INTENDED LEARNING OUTCOMES (ILOs)

On completion of this subject the student is expected to:

• draw flowsheets for appropriate energy systems
• calculate energy and mass flows within such systems
• appreciate the theoretical limits on device performance and determine thermodynamic efficiencies if proposed systems
• perform process optimisation and solve ill-defined process problems related to energy systems

• Four assignments spread throughout the semester, each of no more than 10 pages (10% each)
• One written two-hour end-of-semester examination (60%).

Hurdle requirement: A mark of 40% or more in the end of semester examination is required to pass the subject.

ILOs 1 to 4 are addressed in the assignments.

ILOs 2 and 3 are addressed in the examination.

This subject is not available as a breadth subject.

• Ability to apply scientific fundamentals
• Ability to communicate effectively with the community at large
• Ability to undertake problem identification, formulation and solution
• Ability to use a systems approach to the analysis of operational performance
• Understanding of the social, cultural, global and environmental responsibilities of a professional, and the need for sustainable development
• Understanding of the principles of sustainable design and development

LEARNING AND TEACHING METHODS

The subject will be delivered through a combination of lectures and tutorials.

INDICATIVE KEY LEARNING RESOURCES
