## Research interests

## Research interests

Angela’s main research interest is the theoretical and numerical investigation of fluid flow phenomena. Her current focus is in the following areas

- Drag reduction by superhydrophobic surfaces
- Turbulent flow over rough surfaces
- Lagrangian turbulence statistics
- Numerical methods for computational fluid dynamics
- Control of turbulent flows

**PhD projects**

I have a number of projects to offer to candidates interested in computational fluid mechanics. I can also offer combined numerical and experimental projects which will be co-supervised by colleagues in the Aerospace Sciences Division who are experts in experimental fluid dynamics. Examples for PhD projects are given below.

#### Exploring the effect of energetic turbulent flow structures leading to sediment transport

Over 5 million people in the United Kingdom live in regions of elevated risk from extreme hydrologic events such as flooding and storm surges. These numbers are expected to further increase due to the combined effects of climate change and urbanisation. As weather phenomena intensify, so do the geomorphic processes that are primarily responsible for shaping the Earth’s surface. Such effects can be alleviated by improving the management of rivers and estuaries considering linkages between form and function of the water surface bodies. This however requires a better understanding of the mechanics of sediment transport, so that better numerical tools can be developed to predict these phenomena.

Recent developments have highlighted the role of highly fluctuating turbulent forces on the transport of sediment grains laying on the river bed surface. However, in many established models only a time-averaged representation of the turbulent flow field is considered, failing to take into account the highly intermittent small-scale fluctuations. In addition, the structure of the turbulent flow and the topography of the river bed have a strong influence on sediment transport.

In this project direct numerical simulations will be used to investigate the properties of the instantaneous near-wall turbulent fluctuations in riverbeds and their influence on sediment transport. The numerical results will be compared to experimental measurements and will improve our understanding: a) of flow over different types of bed roughness and b) of flows past flow obstructions of varying structural complexity (e.g. from solid cylindrical piers to flexible-porous vegetation elements).

### PhD scholarships/ funding

The School of Engineering awards a number of PhD scholarships each year via the school scholarship scheme. Projects are usually advertised in autumn and applications close in mid-February. Please note that due to the way these scholarships are funded most scholarships will be awarded to UK students and only a very small number will be awarded to students from outside of the United Kingdom.

Most international PhD students at the School of Engineering are self-funded, e.g. they supported by schemes offered their home governments.

### Erasmus+

If you are a student from the EU and are interested in coming for a project to the School of Engineering you should have a look at the Erasmus+ programme. Please note that the number of places for project students at the School of Engineering is limited - apply early in the academic year!

## Biography

Dr Angela Busse is a Lecturer for Mechanical Engineering in Aerospace Sciences Division at the University of Glasgow. She graduated with a degree in physics from the University of Bayreuth, Germany. From 2006 to 2009 she worked as a research assistant at the Max-Planck-Institute for Plasma Physics in Garching bei München. In 2009 she was awarded a PhD in physics by the University of Bayreuth for a thesis entitled “Lagrangian statistical properties of hydrodynamic and magnetohydrodynamic turbulence”. From 2009 to 2013 she worked as a research fellow in the Aerodynamics and Flight Mechanics research group at the University of Southampton. She joined the University of Glasgow in 2013.
