INVISCID FLUID DYNAMICS - 2021/2

Module Overview

This module introduces students to inviscid fluid flows. By the end of the module, students should be able to recognise dominant features of fluid motion, and to derive some simple solutions of the equations of motion. Students should also have an appreciation of the force balances that produce various classes of flows.

Assessment Strategy

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

• 
  Understanding of the methods required to solve complex fluid flow problems.
  


• 
  Subject knowledge through the recall of definitions as well as explaining the physical nature of flows, and explaining under what conditions certain approximations breakdown.
  


• 
  Analytic ability through the solution of unseen and seen similar problems in the test and exam.
  

 

Thus, the summative assessment for this module consists of:

• 
  One two hour examination (three of four best answers contribute to exam mark) at the end of Semester 2; worth 80% module mark.
  


• 
  One in-semester test; worth 20% module mark
  

 

Formative assessment and feedback

Students receive written feedback via three marked, but unassessed, coursework assignments over an 11 week period.  In addition, verbal feedback is provided by lecturer in lectures and in office hours.

 

Module aims

• Introduce students to inviscid fluid problems including the techniques required to solve such problems.
• Enable students to solve complex problems using a variety of approaches, such as the velocity potential, the complex potential and the stream function.
• Illustrate how the techniques of the module can be applied to more complex situations such as flow over aerofoils.

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to provide:

• 
  A thorough account of inviscid flow techniques under a variety of simple situations, inside and outside simple geometries.
  


• 
  Experience (through demonstration) of the methods and techniques used to solve problems in inviscid fluid mechanics.
  

 

The learning and teaching methods include:

Teaching will be by lectures and problem classes. In addition to reading the lecture notes, students will learn by tackling a wide range of problems. Students should also use the books listed as background reading on the subject.

 

Three hours per week (lectures and problem classes) over an 11 week period.

 

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.
