Collaboration Brunel Solar Team
Brunel Solar Team and Actiflow Join Forces for Success in the Bridgestone World Solar Challenge
The Brunel Solar Team, consisting of 18 students from TU Delft, is collaborating with Actiflow to optimize their latest solar car, the Nuna 13, for the prestigious Bridgestone World Solar Challenge 2025. This 3,000 km race through the Australian outback is one of the toughest in the world, and the team is once again competing for victory this year, after winning seven world titles in 11 editions.
In the lead-up to the race, there are important rule changes, including an increase in the solar panel size from 4 m² to 6 m², and a restriction on the battery size to just one-third of its previous size. Additionally, the race has been moved forward by two months, increasing the emphasis on efficiency and planning.

Improvement of Aerodynamic Performance with CFD Thanks to Collaboration with Actiflow
With around two-thirds of the resistance caused by air, aerodynamics is crucial to the success of the Nuna 13. Thanks to the collaboration with Actiflow, the Brunel Solar Team has been able to take their CFD simulations (Computational Fluid Dynamics) to the next level. Actiflow has not only helped improve the CFD setup but also introduced new technologies that increase the reliability of the simulations. Furthermore, Actiflow has implemented an adjoint-based method for the CFD, enabling the team to further refine the aerodynamics of the Nuna 13.
This collaboration between Brunel and Actiflow is a significant step in the pursuit of the coveted world title, where technology and innovation go hand in hand to optimize the performance of the Nuna 13. The team is looking forward to the challenge of the upcoming race.
