Fluid Mechanics is a fascinating subject that draws physics and maths together and is applied in an enormous range of disciplines, from geophysics to medicine to astrophysics. In this course we will focus on those aspects of high Reynolds number fluid mechanics that are relevant to the practicing engineer and aim to equip the student with the understanding necessary to critically assess the various computational, experimental and analytical approaches to predicting and measuring flow behaviour.

Intended learning outcomes

The intended learning outcomes are grouped into three areas, A: numerical techniques to model high Reynolds number fluids, B: experimental diagnosis, C: analysis techniques. On successful engagement with the unit the participants should be able to:

- Identify the primary reasons for and estimate the magnitude of error accrual and instability in numerical simulation, experiment and theoretical prediction when applied to a canonical turbulent flow (EA2, EA6m). - Describe the key features and implement simple versions of the algorithms that underlie the image data-processing in industry-standard measurement techniques of particle image velocimetry and laser-induced fluorescence and that underlie the upwind finite-volume explicit approach to numerical simulation (EA3m,SM1m). - Develop a version of the industry-standard k-epsilon model for turbulence for use in a one-dimensional numerical model and compare results with analytical predictions, experimental evidence and three-dimensional numerical simulations (EA3m,SM2m). - Appreciate the scaling properties of a massively-parallel numerical simulation and apply techniques to mitigate communication latency in parallel code. Plan and execute a sequence of week-long simulations to evaluate grid convergence of such methods in highly turbulent flows (EA4m, SM3m).
