Mechanical Engineering BEng (Hons)

Module EN0201 - Energy Conversion Systems

(20.00 Credits)

SYNOPSIS OF MODULE
The module introduces the principles of thermo-fluid mechanics and their application to energy conversion systems. The importance of the fundamental principles of thermodynamics for heat and work transfer in a variety of engineering devices will be explored.

The theoretical limitations posed by the Second law of thermodynamics will be explored. A set of laboratory experiments along with seminar activities will be used to highlight the need to appreciate the differences between theoretical calculations and the practical results obtained from real systems.

The module will be delivered via a combination of lectures, seminars, laboratories, and directed and independent learning. Assessment consists of coursework and an examination. The coursework will be an individual written report. The student will receive formative feedback in the lectures on problem solving tasks and throughout the seminars and laboratories.

AIMS OF MODULE
The module introduces the principles of thermo-fluid mechanics and their application to energy conversion systems. The importance of the fundamental principles of thermodynamics for heat and work transfer in a variety of engineering devices will be explored. Students will gain experience of comparing theoretical calculations with experimental results.


LEARNING OUTCOMES
Upon completion of this module the student will be able to:

1. apply the fundamental principles of thermodynamics and fluid mechanics for energy conversion systems.
2. identify and describe the performance of thermo-fluid systems through analytical methods that include the use of empirical relations involving non-dimensional numbers.
3. develop and apply practical engineering laboratory skills.
4. apply a systems approach to engineering problems.

LEARNING AND TEACHING STRATEGY
The module will be delivered using formal lectures, seminars and laboratory sessions. The lectures will cover relevant theory with reference to relevant texts.
A number of seminars and laboratories will be used to enhance the student’s interactive learning experience. The seminars will include exercises designed to develop the learner’s experience of problem solving. During the laboratory sessions students will develop experience of real systems and applications. Formative feedback will be provided on the work undertaken in the seminars and laboratories.




ASSESSMENT AND FEEDBACK STRATEGY
a Summative assessment and rationale for tasks

Summative assessment will be through coursework (30%) and a final examination (70%). The coursework will be an individual report that covers the practical laboratory experiments underpinned by related theories. Whereas the exam will cover more fundamental theory on broader issues of electrical energy, thermodynamic process and fluid dynamics

b. Additional formative assessment – detail of process and rationale

The goal of the formative assessment is to help the student improve their learning and to help them prepare for the summative assessment. It will take place in the lectures, seminars and laboratories.

c. Indication of how students will get feedback and how this will support their learning
