Summary module description:
The objective of this course is to provide an elementary, but rigorous mathematical presentation of continuum description, to introduce concepts and basic principles of fluid mechanics.

Aims:
The objective of this course is to provide an elementary, but rigorous mathematical presentation of continuum description, to introduce concepts and basic principles of fluid mechanics. In particular, the aim is to introduce tensors and elements of tensor algebra, governing equations and their application to modelling and solution of representative fluid mechanical problems relevant to industry and environment, to show various mathematical approaches and assumptions commonly used in the analysis of liquid flows. The module has been developed for students who have little or no experience in fluid mechanics.

Assessable learning outcomes:
By the end of the module students are expected to be able to:
- Use tensor notations and basic techniques of tensor algebra
- Formulate fluid mechanical problems with appropriate set of boundary conditions.
- Use different mathematical techniques to analyse representative fluid mechanical problems relevant to applications in industry and environment studies.

Outline content:
The principles of fluid mechanics are at the heart of numerous natural processes and technological applications ranging from new tools used in emerging technologies, such as micro and nano-fluidics, used in pharmacy, to biological and medical applications of fluid dynamics, modelling of aircraft dynamics and climate research.

The behaviour of a fluid mechanical system is governed, in general, by a set of partial differential equations, the Navier-Stokes equations. In practice, this set of differential equations has to be augmented with boundary conditions in order to obtain unique solutions to particular fluid mechanical problems. The mathematical theory of fluid motion provides techniques for formulating and analysing such problems. Simple examples of such systems are liquid flows in channels, river flows, and flows past solid bodies, such as aircraft wings, vortex motion in the atmosphere. Other applications arise in a wide range of subjects, including biology, microfluidics and aerospace engineering. In this course, the emphasis will be on the systems with simplified geometry and/or that can be modelled by a simplified set of differential equations. During the course, we consider rigorous mathematical foundation of fluid mechanics and then turn our attention to some well-known practical problems.

Content:
1. Tensors, tensor calculus and applications
2. The Reynolds Transport Theorem, the Navier-Stokes equations and admissible set of boundary conditions
3. Static problems, inviscid flows, potential theory, stagnation-point flow, basic two-dimensional potential flows, irrotational flows and origin of lift
4. Scaling analysis, boundary layers, viscous flows
5. Shallow water approximation and water waves

Penalties for late submission:
The Module Convener will apply the following penalties for work submitted late, in accordance with the University policy.
where the piece of work is submitted up to one calendar week after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for the piece of work will be deducted from the mark for each working day (or part thereof) following the deadline up to a total of five working days;
where the piece of work is submitted more than five working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.

The University policy statement on penalties for late submission can be found at: http://www.reading.ac.uk/web/FILES/qualitysupport/penaltiesforlatesubmission.pdf
You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.

Length of examination:
Two hours.

Requirements for a pass:
A mark of 40% overall.

### Course Disclaimer

Courses and course hours of instruction are subject to change.

Some courses may require additional fees.

Credits earned vary according to the policies of the students' home institutions. According to ISA policy and possible visa requirements, students must maintain full-time enrollment status, as determined by their home institutions, for the duration of the program.

ECTS (European Credit Transfer and Accumulation System) credits are converted to semester credits/quarter units differently among U.S. universities. Students should confirm the conversion scale used at their home university when determining credit transfer.

Please reference fall and spring course lists as not all courses are taught during both semesters.

Please note that some courses with locals have recommended prerequisite courses. It is the student's responsibility to consult any recommended prerequisites prior to enrolling in their course.
