CEG8517 : Computational Hydraulics
- Offered for Year: 2019/20
- Module Leader(s): Dr Caspar Hewett
- Lecturer: Mr Vassilis Glenis
- Owning School: Engineering
- Teaching Location: Newcastle City Campus
|Semester 2 Credit Value:||10|
The aim of this module is to provide an understanding of numerical methods applied to problems in hydraulics. It is designed to provide a good understanding of the strengths, weaknesses and limitations of the methods which underpin mathematical models of real systems.
Students will acquire the necessary skills to use computational hydraulics software to solve engineering problems with competence and confidence.
The module will introduce a variety of numerical methods using a series of problems including advection (transport of a dissolved substance) and diffusion. Topics covered will include:
• The method of characteristics,
• Finite difference, finite element and finite volume methods;
• Analysis of convergence, stability and accuracy of numerical schemes.
The above aims will be achieved by adopting a combination of lectures, tutorials and computer-based workshops.

Teaching Rationale And Relationship
Lectures allow knowledge transfer of the various numerical and modelling methods available for application in the hydraulics discipline, and computer-based practicals allow for consolidation of this knowledge prior to its application in the development of simple software and its application to given problems (which is carried out as coursework).
The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship
Assessed by written examination and coursework. This allows a student's knowledge and understanding of the methods introduced to be monitored, applied and tested.
Assessment is split between:-
(a) Practice questions worked through in lectures (formative);
(b) (Coursework – Written reports of exercises carried out in workshops;
(c) Coursework - which monitor understanding of ;
(d) Exam - Which assesses knowledge and skills in numerical methods.
The rationale is to assess the students’ grasp of the practical skills and understanding represented by the knowledge outcomes. Practical submissions are assessed to emphasise importance of completion of the practical tasks for development of intended skills. The written exercise involves development of simple numerical method which assesses skills in development of the methods and their limitations. The unseen exam assesses knowledge of basic numerical methods used in Computational Hydraulics.
