TURBULENCE - 2021/2

Module Overview

This module builds on earlier fluids modules and on the ‘Numerical Methods and CFD’ year 3 module. The module provides an introduction to the physics of turbulent flows, their prediction and experimental study. Practice is covered through CFD case studies and a related assignment.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate

understanding of the scientific principles, and mathematical methodologies used in the study of turbulence. The CFD coursework element allows students to demonstrate that they can interpret a problem, conduct a CFD analysis at the level used in the aerospace industry, and present a report of the solution clearly and accurately.

Thus, the summative assessment for this module consists of:

·         CFD assignment        [ Learning outcomes 3, 4 ]                  (45 hours)        {40%}

·         Examination               [ Learning outcomes 1, 2, 3, 4, 5 ]      (2 hours)          {60%}

 

Formative assessment and feedback

• Formative verbal feedback is given in tutorials


• Written feedback is given on the CFD assignment 

Module aims

• provide a general understating of turbulence and the nature and structure of turbulent flows
• introduce turbulence modelling and its application in CFD, including practical experience in its use
• introduce experimental techniques for investigating turbulent flows

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

introduce the basic principles of turbulence through theory with worked examples. This is delivered principally through lectures and tutorial classes. Practice is covered through CFD case studies and a CFD assignment solving a basic aerospace test case.

The learning and teaching methods include:

• 20 hours lectures (weeks 1-11)


• 24 hours tutorials (weeks 1-11)


• 2 hours revision lectures (week 12)


• CFD assignment (45 hours)
   
  

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
