Aims |
|
This module gives an introduction to the mathematical theory of linear and non-linear waves. Illustrative applications involve problems of acoustics, gas dynamics and examples of solitary waves. |
Learning Outcomes |
|
(LO1) Apply essential modelling techniques in problems of wave propagation. |
|
(LO2) Analyse how mathematical models of the same type can be successfully used to describe different physical phenomena. |
|
(LO3) Master background mathematical theory used in models of acoustics, gas dynamics and water waves. |
|
(S1) Problem solving skills |
|
(S2) Numeracy |
