Bruño Fraga is a Lecturer of Numerical Modelling in the School of Engineering.

Bruño is a prominent researcher in the field of Computational Fluid Dynamics. He has developed several in-house codes and has published in some of the best journals of the field with collaborators from UK, US, and European institutions. His main expertise is the study of Turbulence, particularly in multi-phase flows, where liquids, gas and solids interact.

He is a passionate lecturer who tries to incorporate examples and some of the newest technological applications in the teaching of Fluids and Hydraulics. He is currently 4th year convenor, head of the CFD Special Interest Group in the University of Birmingham, and member of the Ethics Committee of the University.


Bruño qualified with a MEng (Hons) and a National Award in Environmental Engineering in Santiago de Compostela University (Spain) in 2007. He obtained a MSc with a merit in Mathematical Engineering and Numerical Simulation in 2009 and started a PhD little after.

His PhD was focused on 3D modelling of flow in natural rivers and open-channel bends, using different turbulence modelling approaches. He was able to self-fund his PhD and spend some time in the universities of Chalmers (Sweden) and Cardiff (UK), where he had his first contact with large-eddy simulation models.

In 2013 Bruño moved to Cardiff University hired as a postdoctoral Research Associate under the supervision of Professor Thorsten Stoesser. His first project during that time consisted in simulating the near-field release of the oil-gas plume created by the blowout of the DeepWater Horizon platform in the Gulf of Mexico. After that, he worked in advanced modelling of scour prediction in rivers, but he would continue to develop work in the field of multiphase flow in parallel. He also worked in the development of hybrid parallelisation techniques for computation.

In 2017 Bruño was appointed as a Lecturer in the University of Birmingham. In 2018, he was a visiting scholar at Stanford University developing a ground-breaking project regarding the physics of bubbly flow in the Centre for Turbulence Research hosted by this university in collaboration with NASA, among others.
