Learning Outcomes

On completion of this module students should be able to:1. To understand and apply the fundamental principles of thermodynamics and fluid mechanics, and to support understanding of future developments in energy conversion systems. 2. To be able to understand the concept of a heat engine and apply the principles of the Second Law of thermodynamics 3. Recognise the significance of the Carnot cycle and evaluate basic ideal vapour and gas power cycles.4. To be able to evaluate energy transfer for incompressible flow in basic pipework systems including energy losses caused by pipe fittings and friction. 5. To be able to apply the laws relating to one dimensional steady state heat transfer involving heat transfer through composite plane walls and composite cylinders

Teaching / Learning Strategy

To support the student learning experience this module's lectures and seminars are carefully structured to present a consistent and logical progression of topics and concepts. The lecture delivery will be enhanced by a variety of forms including, where appropriate, computer based animations and other multimedia forms. Feedback will be provided to students as follows: Students will be provided with feedback within two weeks of submission of all summative assessments providing information on strengths, weaknesses and suggestions for corrective action. Student feedback on teaching, learning and assessment will be sought at the end of the semester through a module evaluation questionnaire
