Short Description

Main Assessment In: December

Are reassessment opportunities available for all summative assessments? Not applicable

Reassessments are normally available for all courses, except those which contribute to the Honours classification. For non Honours courses, students are offered reassessment in all or any of the components of assessment if the satisfactory (threshold) grade for the overall course is not achieved at the first attempt. This is normally grade D3 for undergraduate students and grade C3 for postgraduate students. Exceptionally it may not be possible to offer reassessment of some coursework items, in which case the mark achieved at the first attempt will be counted towards the final course grade. Any such exceptions for this course are described below. 

Course Aims

This course aims to enhance students' understanding of viscous fluid flows and to develop the skills necessary for the application of basic analytical and numerical simulations of such flows.

Intended Learning Outcomes of Course

By the end of this course students will be able to:

■ identify the limitations of ideal flow modelling in the case of streamlined and bluff bodies;

■ derive the fundamental equations of fluid motion and demonstrate understanding of the terms involved;

■ perform an order of magnitude analysis of the fundamental equations as they apply to flow in attached boundary layers;

■ develop and apply solution methodologies for both laminar and turbulent boundary layer equations;

■ describe the main features of the transition process in boundary layers;

■ explain the process of Reynolds averaging, and apply to the equations of motion;

■ describe the nature of the turbulence closure problem, and critically assess some basic models for addressing this problem.

Minimum Requirement for Award of Credits

Students must attend the degree examination and submit at least 75% by weight of the other components of the course's summative assessment.


Students should attend at least 75% of the timetabled classes of the course.


Note that these are minimum requirements: good students will achieve far higher participation/submission rates.  Any student who misses an assessment or a significant number of classes because of illness or other good cause should report this by completing a MyCampus absence report
