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. Non-dimensional analysis methods, laminar and turbulent flows and pipe system analysis are considered, including fluid friction, momentum and energy losses in fittings.

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 content

Indicative content includes:

Fluid Mechanics

Fluid properties (density, viscosity, surface tension)

Hydrostatics (forces on surfaces, submerged bodies, valves, gates etc.)

Buoyancy (stability of submerged and floating bodies)

Fluid kinematics (streamlines and continuity)

Fluid dynamics (Bernoulli’s equation, flow through orifices, Venturi meter)

Momentum equation (impacting jets, forces on pipe bend)

Introduction to viscous laminar & turbulent flow (Re, laminar flow, Poiseuille flow in a pipe, description of turbulent flow characteristics) [10hrs]

 

Turbulent flow

        Film model and 1/7th power law for time averaged flow in pipes

        Friction factors and pressure gradients in pipes
                    (effect of roughness; Moody chart)

        Hydrodynamic resistance of sudden expansions, valves, bends etc.

        Introduction to boundary layers on a flat plate, including variation of shear stress with distance from leading edge. 

Pumps

            Types of pumps

            Head/flow rate characteristics (esp. centrifugal pumps)

            Pumps in series and parallel  (includes mention of NPSH)

            Simple Pump and pipe-work calculations

 

Dimensional analysis (Buckingham’s Pi theorem)

            Scale models [12hrs]

   

Thermodynamics

            Introduction to thermodynamics – work & heat transfer

            Energy consumption, generation, alternative sources and system efficiency

            First law  – for closed systems, internal energy. Applications.

            Steady flow energy equation, enthalpy.

            Applications to power plant (pV diagrams)

Fluid properties, liquids & gases, Cp and Cv  [11hrs]

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 concludes with an independently conducted mini project involving basic experimental procedures.

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
Thermo mini project 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 coursework element allows students to demonstrate that they can interpret a problem and present a solution clearly and accurately. The mini-project tests research skills and report writing as well as their ability to record a simple experiment and comment critically on accuracy and methods employed.

Thus, the summative assessment for this module consists of:


Fluids coursework      [ Learning outcomes 1, 2 ]                  {15%}
Thermo mini-project  [ Learning outcomes 3, 5 ]                   {15%}
Examination               [ Learning outcomes 1, 2, 3, 4 ]         (2 hours)   {70%}


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 including a TurnItIn report on their Thermo mini-project
