Swapping Fuel for More Beer on your next Caravan Holiday

Caravan owners are well aware that the speed they drive at and the shape of their caravan can greatly affect fuel consumption.
In partnership with Caravan World magazine, we've taken a closer look into the performance of caravans with the aid of CFD, including some less obvious factors that can help shave off the drag on your caravan and improve fuel consumption.

Can CFD help to solve Australia’s greatest aviation mystery?

Can CFD help to solve Australia’s greatest aviation mystery?

On a stormy night in August 1981, a Cessna Centurion 210 aircraft crashed with 5 people on board in Barrington Tops, a rugged and isolated national park north of Newcastle, New South Wales.  Despite a massive initial search effort and ongoing attempts by a group of dedicated volunteers, the challenging and complex terrain has conspired to prevent the wreckage from ever being found. To put this into some perspective: according to Corporal Mark Nolan (Pilot, Australian Army), this is the only aircraft to have crashed on mainland Australia and never be recovered.  We can only imagine how frustrating and heartbreaking this must be for the victim’s families to be denied this closure. One of the biggest factors that has inhibited previous search attempts is the rugged, dense bushland in the Barrington Tops national park. NSW Police Superintendent Peter Thurtell confirms that “the terrain out there is as rugged as anywhere you'll find in Australia.”  Importantly, he notes that the primary search area has two steep ridges that makes it particularly difficult to get in and out each time, furthering hampering the efficiency of any search efforts. However, with recent advances in technology and some novel use of computational fluid dynamics using ANSYS ICEM and ANSYS CFD, we hope that this mystery is about to be cracked wide open.  This coming weekend, the concerted efforts of numerous professional and volunteer organisations (including Police Rescue, National Parks and Wildlife, NSW Rural Fire Service, NSW State Emergency Service and the Bushwalkers Wilderness Rescue Squad) will combine to have over 100 members on the ground searching for the elusive wreckage of Cessna 210M VH-MDX. Police Superintendent Peter Thurtell adds that while the team is not overly confident, a lot of planning has been done and he now believes "we've identified an area that gives us the best chance of locating the plane." At this point, you may ask how CFD has contributed to solving this 32 year-old mystery? In advance of this major search operation in October 2013, the search coordinators recently undertook a major push to evaluate all the available evidence and comprehensively review all of the theories about what happened to the aircraft. The technology involved includes side-scan sonar of the Chichester Dam, high-resolution aerial photography as well as LIDAR scans of the likely crash site. After painstaking evaluation of the available evidence, the likely crash site was narrowed down significantly by a team of 5 people, including a Police Rescue intelligence officer, a Police GIS officer, a Navy Pilot, a 1981 Air traffic control operator and a dedicated volunteer, Glenn Horrocks, who just happens to be a specialist CFD engineer (in his ‘day...

Formula SAE teams aim for the podium with CFD

Budding F1 car designers & engineers here in Australia may be getting excited in the build-up to the first race of the F1 season with the Australian F1 Grand Prix being held in Melbourne next week (March 14-17), but many of them might also have another important car race in the back of their minds: the 2013 Formula SAE (FSAE) competition, which is the world’s largest student engineering design competition.   Starting in 1979 but really gaining in popularity here during the past 15 years, Formula SAE invites highly-motivated engineering students from leading universities around the world to design, manufacture, test and race their own single-seat racecar. Each car is judged for dynamic performance including acceleration, autocross, endurance, fuel economy as well as other important engineering and business-related metrics such as cost, marketing and design philosophy.   We've previously covered the impact of CFD technology on Formula 1 racecar design, but it is clear that CFD technology provides just as much benefit to the leading Formula SAE teams.  In Australia, LEAP is proud to be closely associated with many of the local Formula SAE teams, including Monash Motorsport and Team Swinburne FSAE.  In particular we'd like to recognise the passion and success of the Monash Motorsport team, who together with Team Leader Scott Wordley have won the past 4 Australasian FSAE titles, and are now ranked 2nd globally (out of 510 graded university teams)!   CFD has formed a pivotal contribution to the design and testing of the aerodynamic package designed for the most recent Monash FSAE car (shown left, image courtesy Monash Motorsport & Mitchell Stafford), which incorporates imposing front and rear wings and a clever floor diffuser.  In any racecar design, competing design goals set the scene for a constant battle to provide maximum downforce for superior braking and cornering performance, without sacrificing raw speed due to increased aerodynamic drag.   Inspired by Formula 1 and refined using CFD, one of the 2013 car's secret weapons is a drag-reduction system (DRS) that automatically changes the angle of attack of the main wings at a certain speed to reduce drag when the car approaches top speed down the straight.   Despite its competitive nature, our observation at LEAP is that Formula SAE is also a remarkably close-knit community as evidenced when Monash Motorsport have generously hosted other teams in their workshop and also given other teams access to their world-leading wind tunnel facilities.  In conjunction with Monash Motorsport, LEAP Australia is preparing to host a special workshop in April covering the use of ANSYS CFD and FEA software for Formula SAE car design.  The 3-day workshop "DESIGN TO WIN" will be held April 2nd-4th at Monash Clayton campus and students from all Formula SAE teams...
