Summary of Content

The aim of this module is to provide students with a foundation in the knowledge of mechanical engineering science and principles, and apply them to the design and analysis of hydrostatic, hydrodynamic and thermodynamic systems.

Syllabus

The teaching syllabus will cover the following areas: Introduction to Thermofluids: Definition of a fluid. Ideal and real fluids. Perfect gases. Compressible and incompressible fluids. Dimensions and units. Distinction between a fluid and a solid. Shear stress, velocity gradient and viscosity. Newtonian and non-Newtonian fluids. Description of phase. Fluid as a liquid, gas or vapour. Fluids: Fluid statics. Pressure in static fluids. Measurement of pressure, manometry. Descriptive treatment of flow. Comparison of laminar and turbulent flow. Reynold's Number. Continuity, momentum and energy equations. Use of energy equation to analyse single pipe systems. Thermodynamics: Basic definitions of systems. The perfect gas. The equation of state for a perfect gas. The 1st law of thermodynamics. The non-flow energy equation. Application to constant volume, constant pressure, isothermal, isentropic and polytropic processes.

Learning Outcomes

On completion of this module the student should be able to:1. demonstrate an understanding of fluids and their basic properties;2. measure and calculate fluid pressure;3. analyse flows, pressures and energies in pipe systems;4. apply the principles of work and energy in compressible fluid flow systems;5. evaluate heat, work and energy terms for closed systems using the 1st law of thermodynamics.

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.
