2017 World Solar Challenge: proudly supporting student teams on their adventure of a lifetime

Many of the world’s best solar car teams are on track to reach Adelaide today, 4-5 days after they started their journey in Darwin on Monday, and 2+ years after commencing their initial planning and engineering design following the 2015 competition.

Firstly, we'd like to send massive congratulations to the teams who have already finished yesterday, especially the Delft team who won overall line honours:

Challenger Class: Nuna9, Nuon Solar Team from Delft University who have continued their successful record in the Challenger Class (once again sponsored by ANSYS!) and claimed their seventh title - crossing the Official Finish Line in Victoria Square Adelaide, first in 2017 and after achieving an impressive average speed of 81.2 km/hr over the journey from Darwin to Adelaide!!

Cruiser Class: At this stage, Stella Vie, Solar Team Eindhoven also look set to build upon their history of success in the Cruiser Class (also again sponsored by ANSYS), with a massive efficiency score of 80 (compared to 34.6 for the next best team in this class)!  Read more about the engineering simulation background to their victory in 2013 from the ANSYS Blog.

 

LEAP would also like to extend our congratulations to all the Australian teams who have embarked on this adventure in the 2017 World Solar Challenge: especially the teams we have been closely involved with below.

Amidst the confetti at the finishing line, it can be easy to lose sight of all the hard work and engineering effort that goes into this competition, so below we have included some interesting details of simulation work that is undertaken by the teams.  As an example, in just their 3rd event, the Western Sydney Uni team is currently on track in 2017 to deliver its best ever result – well done to everyone involved and we hope you all enjoy a well-deserved beer (or a bottle or two of Mt Bera wine) in Adelaide tonight!

 

  • UNSW Sunswift: Read more on UNSW Sunswift’s exploits in 2013/14 here from our blog.  “LEAP Australia were a huge part in the creation of eVe, offering professional expertise and training in computational fluid dynamics and aerodynamics design.”
  • AUSRT from Adelaide Uni“Lumen II has placed an emphasis on aerodynamics design. A leaner and sleeker layout, with improvements particularly in the fairings and the edges of the body, has allowed the aerodynamic drag to be cut by 40% from Lumen.  With all these changes, we expect Lumen II to run significantly faster than Lumen - but there's only one way to find out: bring on the race!”
  • Clenergy Team Arrow (QUT): “ANSYS has been used  to model the aeroflow of new wheel covering design. Using ANSYS proved to assist significantly in ensuring we had the most aerodynamic design within the constraints of the vehicle. As we begin to develop our new car for 2017, we continue this process to ensure our car is aerodynamically efficient to create the best possible solar vehicle we can.”
  • Western Sydney Uni solar team: “ANSYS Fluent has been instrumental in the aerodynamic shaping of our new car. Particularly without access to a wind tunnel, we rely on ANSYS’s capabilities, and it has allowed us to reduce our drag by 40% from our previous car. ANSYS Mechanical was also essential in predicting whether our parts would be capable of withstanding the forces they are subjected to, and for optimising our parts for weight reduction based on this feedback.”
