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

The world’s best solar car teams are driving into Adelaide today, 4-5 days after they started their journey in Darwin, and 2+ years after commencing their initial planning and engineering design following the 2015 competition. Congratulations to all the teams - read more about the simulation work done by committed student teams in the lead-up to this pioneering race.

Guest Post: ANSYS CFD helps Sunswift tackle the World Solar Challenge

Issue 1 of ANSYS Advantage magazine places the spotlight on the academic use of CFD and other ANSYS software.  Part of this issue is dedicated to student engineering competitions where students have the chance to use real-world engineering methods and tools such as CFD to design cutting-edge products, including race cars (FSAE) and solar passenger vehicles (World Solar Challenge).  Many of you may know that LEAP Australia has for years been a strong supporter of the University of New South Wales' Sydney-based Solar Racing Team - otherwise known as Sunswift - especially during the design and development of their latest car, Sunswift eVe. LEAP provides students with training and mentoring in CFD and FEA software, and helped implement effective CAD-to-CFD workflows and optimisation approaches in Workbench.   In this guest post, Dr. Graham Doig of UNSW's School of Mechanical and Manufacturing Engineering shares further insights into Sunswift's use of ANSYS CFD software to design what is one of the world's lowest-drag passenger vehicles. Dr. Doig is the academic supervisor for the race-winning, record-holding team - he teaches CFD and experimental aerodynamics as well as leading research at the Fluids Laboratory for Interdisciplinary Projects, and guided the core solar car aerodynamics crew of undergraduate engineers Pujith Vijayaratnam, James Keogh, Taryn Zhao and Matt Cruickshank, who were also mentored by former Formula One CFD engineer and Sunswift alumnus Dr. Sammy Diasinos of Macquarie University. Sunswift is a student-run project to design and build solar racing cars. The flagship event for the solar car fraternity is the biennial World Solar Challenge (or WSC) rally, a silent gruelling zoom across outback Australia - 3000kms from Darwin in the Northern Territory to Adelaide in South Australia - using the power of the sun to propel an international assortment of between 40 and 50 vehicles ranging from the sleek to the wacky. Power is extremely limited, so aerodynamic efficiency is king.   Sunswift started out in the mid-1990's, and in recent years has had an astonishing run of success - in 2009 our one-seater prototype Sunswift IVy won its class in the WSC, repeating that feat in 2011 and breaking a Guinness World Record for the Fastest Solar-Powered Vehicle in the interim. Put simply, we felt we'd taken things as far as we could building the "traditional" spaceship-like vehicles that have dominated solar car racing in the modern era. Basically a wing covered in solar panels with shrouded wheels underneath, European and Japanese cars of this design with several times the budget of our Aussie underdogs had been able to use satellite-grade solar cells and expensive, cutting-edge battery technology to beat us comfortably in the overall standings, despite...
