Specification

Aims

This course aims to build on the knowledge and skills developed in Thermofluids 1, with the aim of being able to size and specify components for fluid and thermal systems, so preparing the student with the knowledge and skills necessary for a practicing professional Engineer;

Learning outcomes

On successful completion of this course a student will be able to:

1 Evaluate the performance of power cycles, gas power cycle and vapour power cycle
2 Analyze power generation coupled with process heating called cogeneration.
3 Explain the concepts of refrigerators and heat pumps and the measure of their performance including the ideal and actual vapour-compression refrigeration cycle.
4 Demonstrate the ability to design thermofluid systems;
5 Apply dimensionless numbers to fluid dynamic problems;
6 Evaluate drag on bluff and steamlined bodies;
7 Present and discuss solutions for complex problem exercises;

Indicative content

Vapours Power Cycle:
Representation of properties in tables, diagrams and empirical formula.
The application of the properties of steam to develop practical vapour expansion cycles from Carnot cycle through the Rankine cycles.

Refrigeration cycle:
The application of 'suitable' fluids for heat pumps and refrigerators
Vapour compression refrigeration cycle
Selection of appropriate refrigerant for specific application

IC Engines:
Principle of operation of SI, CI and gas turbine engines, their 'cycles' and applications.
Principle of Otto, Diesel and Brayton Cycles
Case study based on renewable energy

Heat Transfer:
Defining the modes of heat transfer.
Steady state conduction through single and composites of simple geometries.
Properties of conductors, insulators, lagging.
Introduction to convection via film or surface heat transfer coefficient.

Fluid Mechanics:

Extend previous knowledge of fluid statics to consider fluid dynamic applications
Steady laminar / turbulent flow in pipelines
Drag and lift on solids for solids handling applications
Flow measurement and control theory (case study)

Teaching and learning activity

Formal lectures and tutorials will be provided. Fundamental concepts will be introduced in lectures, emphasized through case studies, lab classes and discussions in tutorials. Tutorials will provide an opportunity for the students to demonstrate their new skills and knowledge. A comprehensive laboratory practical programme will further aid understanding of the subject matter in addition to developing essential practical skills. Case studies and problem solving exercises will be set on the topics covered as a group activity or an individual one which is based on the practical application side of the subject matter.
