Short Description

This course develops the fundamental equations of slightly viscous fluid flow, and applies these equations to problems in laminar and turbulent flows, boundary layers in particular.


2x1 hour lectures per week

80% Written Exam

Main Assessment In: December

Course Aims

To enhance 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.
