Module overview

First year common module in thermo-fluids for MES + Chemical Engineering students

FLUID MECHANICS: The basic concepts underlying fluid flows and behaviour are described together with simple fluid properties. The calculation of static fluid forces is the starting point before moving to dynamic fluid effects including mass-flow and energy conservation. Internal flows in pipes and through pumps considering effects of fluid friction, momentum and energy losses in fittings. A range of pumps will be described and how they can be matched to system requirements. This will include non-dimensional analysis methods, laminar and turbulent flows and pipe system analysis.

THERMODYNAMICS: Following an introduction on energy consumption, generation and supply from conventional and alternative sources the basic principles of heat and work transfer are described and system thermal efficiency. Thermal properties of working fluids (both liquids and gases) are described. The 1st law of thermodynamics is introduced with applications to processes and cycles for closed and steady-flow systems.

Module aims

An introduction to fluid mechanics and thermodynamics and in particular internal flow behaviour and the principles and methodologies applied to fluid statics, dynamics and 1st law thermodynamics

An understanding of the principles of energy generation, conservation, conversion and alternative energy sources

An introduction to the importance of system efficiency and minimization of resource requirement in engineering system design

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

Introduce thermo-fluid principles through theory with worked examples. This is delivered principally through lectures and tutorial classes and feedback from coursework assignments.

The learning and teaching methods include:

3 hours lecture per week x 11 weeks

1 hour tutorial (in groups) x 11 weeks

2 hours revision lectures

Fluids coursework (6 hours) submitted on SurreyLearn

Thermo coursework (6 hours) submitted on SurreyLearn

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate understanding of scientific principles, methodologies and mathematics methods as well as the ability to describe particular systems and processes in the final examination. The Fluids and Thermo coursework elements allow students to demonstrate that they can interpret a problem and present a solution clearly and accurately.

Thus, the summative assessment for this module consists of:

· Fluids coursework [ Learning outcomes 1, 2 ] (6 hours) Deadline c. W7 {10%}

· Thermo coursework [ Learning outcomes 1, 2, 3 ] (6 hours) Deadline c. W10 {10%}

· Examination [ Learning outcomes 1, 2, 3, 4 ] (2 hours) {80%}

Formative assessment and feedback

Formative verbal feedback is given in tutorials

Formative Multiple Choice Tests are available on SurreyLearn to give feedback on understanding of simple principles

Written feedback is given on the coursework assessments
