Aerodynamics and propulsion
BAC addresses challenges arising from the fundamental nonlinearity of fluids, their interaction with the human and natural environment, and their use in the generation of thrust. We seek to extend capability in the analysis, simulation, and measurement of fluid flows, building on a long history of major contributions to computational and experimental fluid dynamics.
Why it matters
Aerodynamics is fundamental to innovation in transport, green power and the built environment. BAC helps partners understand the impact of aerodynamics on the efficiency, safety and comfort of their designs.
We help optimise designs in a multidisciplinary world, getting to the heart of engineering problems and delivering reliable results when accuracy matters. Drawing on broad analysis experience, we use the right tool for the job, whatever the challenge.
What this theme focuses on
Our developments have impacted a huge range of applications, from supersonic aircraft to wind-assisted propulsion for shipping and wind turbine power generation. Similarly, the fidelity of the analysis ranges from low-order potential solutions to Direct Numerical Simulation; from total force measurement to detailed velocity distributions within small-scale flow structures. Areas of research include:
- Fundamental techniques: Development of new ways of calculating and measuring flow quantities continues, impacting all research areas within BAC.
- Multiphysics modelling: Strong collaborative links within BAC and beyond have provided a long history of aerodynamic coupling such as: aeroservoelastic, aerothermal and combustion modelling.
- Optimisation: Design can be framed as an optimisation and our work has helped develop and refine many gradient, agent-based and machine learning techniques. These have been applied to a range of applications within aerospace and beyond.
- Computational efficiency: The best solution is one you can afford. Work continues in areas such as computer architecture, meta and reduced order modelling, and AI and machine learning enhanced simulations.
- Surface definition and mesh generation: The sensitivity of aerodynamics to geometry has made this area one of the biggest bottlenecks in aerodynamic related design. Significant work has developed a range of techniques to couple the flexibility needed as a design evolves with the fidelity required for accurate simulation.
Whilst the aerodynamics of propulsion is one of the many facets of BAC, of particular interest is the decarbonisation of aerospace. See our research in the area of electrical power systems.
