|Semester 2 Credit Value:||15|
The module introduces students to a range of thermofluid topics:
- Review of key thermodynamic concepts.
- Heat Transfer.
- Mixtures, Psychrometry and Air-conditioning
- Introduction to fluid mechanics
- Sustainable energy management.
Outline Of Syllabus
Review of key thermodynamic concepts:
- Work, energy, heat, temperature.
- General energy equations.
- Energy transformations (First Law, simple process models).
- Second Law and “grade” of energy.
Mixtures, Psychrometry and Air-conditioning
- Revision of mixtures of vapours and gases
- Psychrometry and air conditioning.
- Cooling tower design.
- Modes (conduction, convection, radiation).
- Thermal resistances (parallel, series).
- Conduction (modelling requirements, 1D steady-state, lumped transients).
- Heat exchanger design.
Introduction to Fluid Mechanics:
- Momentum equation and applications of momentum equation.
- Laminar and turbulent pipe flow.
- Reynolds number and transition.
- Friction factors for laminar and turbulent flow (Moody diagram).
- Local losses and pipe systems.
Sustainable Energy Management:
- Introduction to energy efficiency methods and energy conservation technologies.

Teaching Rationale And Relationship
Lectures (with supporting problem classes) convey the underlying engineering sciences and their application methodologies.
Design assignments (heat transfer, thermodynamics or fluid mechanics) and practical activity (cooling tower, air conditioning, heat transfer or fluid flow) focus on the ability to transfer underpinning knowledge and understanding into engineering application within an industrial context.
The format of resits will be determined by the Board of Examiners
|Practical/lab report||2||M||20||Two laboratory reports (max 7.5 hours).|
|Design/Creative proj||2||M||20||2 design reports at 10% (approx 1000 words each).|
Assessment Rationale And Relationship
End of module examination assesses synoptic understanding and problem-solving skills under time constraint as required in industry.
Case study, design assignments and practical enable more realistic engineering problems to be set and integrate specific content with generic information acquisition, data analysis and reporting skills.
