DESCRIPTION - summary of the module content

This module introduces you to vector calculus and its applications, especially fluid dynamics. It consists of two parts, which are closely linked. In the first part of the module, you will learn about the mathematical theory and techniques of vector calculus. You will develop your competence in using vector calculus in both differential and integral forms. The second part of the module gives an introduction to fluid dynamics as an application of vector calculus. It lays down some basic principles using a number of simplifying assumptions. The module will emphasise inviscid, incompressible flow; later modules will cover the subject of viscous flow.

This module is a prerequisite for a number of more specialist modules in the third year.

Prerequisite modules: MTH1002 and MTH2003 or equivalent

AIMS - intentions of the module

This introductory vector calculus course aims to increase your understanding of fluid dynamics. It examines how one can use vector formalism and calculus together to describe and solve many problems in two and three dimensions. For example, the rules that govern the flow of fluids can be described using vector calculus, with resulting laws of motion described by partial differential equations rather than ordinary differential equations.

INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)

RE-ASSESSMENT NOTES

If a module is normally assessed entirely by coursework, all referred/deferred assessments will normally be by assignment.

If a module is normally assessed by examination or examination plus coursework, referred and deferred assessment will normally be by examination. For referrals, only the examination will count, a mark of 40% being awarded if the examination is passed. For deferrals, candidates will be awarded the higher of the deferred examination mark or the deferred examination mark combined with the original coursework mark.
