Going with the Flow

The water industry has a range of engineering challenges and specific regulatory requirements, especially concerning flow assurance, water quality, and even component selection. Learn how CFD delivers real value to the water industry - such as predicting complex flow behavior, across individual components or large network systems.

Astute use of ANSYS CFD contributes to the success of Australian teams at F1 in Schools 2013 World Finals

LEAP is very proud to congratulate the students from A1 Racing for winning the F1 in Schools 2013 World Finals in Austin, Texas.  A1 Racing are a collaboration team between Pine Rivers in Brisbane, QLD, and Phoenix P-12 in Ballarat, Vic, who have continued the proud tradition of Australian students excelling at this international event by becoming the third successive Australian-based team to win the World Finals (with previous winners hailing from Tasmania and South Australia). In our last post, we mentioned that the use of CFD for aerodynamic design and stability at A1 Racing had already brought some early success, with their team having won the fastest car competition by leading the timetrial event.  Later that evening, it was announced that A1 Racing was also the overall winner of F1 in Schools 2013 World Finals. Let’s go into some more detail on how LEAP’s CFD simulations may have assisted A1 Racing to design the fastest car at the F1 in Schools competition. To begin with, a detailed steady-state analysis was performed in order to evaluate the cars aerodynamic performance in terms of lift, downforce and pitching moment.  By nondimensionalising the lift, downforce and pitching moment, the aerodynamic performance at any speed could be calculated and used to rank the different conceptual designs. It was shown that the most critical factors in obtaining accurate results in these initial studies was in creating a high-fidelity boundary layer mesh for the entire car, and also applying the advanced turbulence modelling capabilities of ANSYS to accurately predict regions of flow separation and the formation of vortices in the wake. Additionally, in order to most accurately reproduce the race conditions for the track, more realistic boundary conditions were applied such as: - a moving ground plane - rotating wheels - inclusion of exhaust gases from the CO2 canister that provides thrust to the car (It was found that in preliminary tests that this stream of high-velocity gas had a large influence on the wake profile, and therefore needed to be included to accurately predict the drag force acting on each car design). In addition to these “straight-line” CFD simulations, the cars were also simulated in a number of different orientations to evaluate the static stability of the car. The car was simulated for both zero angle, small angle and large angle perturbations of pitch and sideslip.. These combinations of different pitch and sideslip perturbations gave the designers a total of nine unique design points which were automatically run in a parametric study of the car’s stability using ANSYS DesignXplorer. Using this approach, the full matrix of simulation results were completed with design point each providing values...

Congratulations to Australian teams in F1 in Schools 2013 World Finals

At LEAP we have a long-standing relationship with all the major universities in Australia and New Zealand.  Our participation extends from the supply of best-in-class engineering software to other important activities such as guest lectures and hands-on workshops/training classes for both academic staff and students.  We also have an ongoing commitment to regularly employ new graduate engineers, many of whom have made their interest in CAE known to us during these earlier on-campus visits. Our frequent interactions with university staff and students have served to underline the importance of the effective teaching of science, technology, engineering and mathematics (STEM) related subjects.  Indeed, we can see how an early passion and engagement in these STEM subjects can make all the difference to help a student successfully pursue a career in engineering and help create our next generation of innovators (which, in turn, strengthens our economy through these design & innovation skills that many commentators have shown are currently lacking). To help boost interest in these STEM subjects, LEAP is pleased to announce our participation in the 2013 F1 in Schools competition through in-kind support (comprising a series of detailed 3D CFD simulations) to the 3 Australian teams who are competing in the World Finals in Austin, Texas: A1 Racing - collaborative team comprising Phoenix P-12 College in Ballarat, Vic, and Pine Rivers State High School, Queensland Motion Racing - students from Engadine High School, Sydney Odyessy - collaborative team comprising Brighton Secondary College, South Australia, & Donavate Community College, Ireland. By all accounts, the Australian students have enjoyed their whirlwind trip this week in Austin, which culminates tonight in the final award ceremony at midnight AEDT.  You can view the awards ceremony webcast live on YouTube.  The use of CFD for aerodynamic design and stability at A1 Racing has already brought some early success with A1 Racing having the fastest car in the timetrials earlier this week, and we'll know more about the other judging components (and overall winners) after tonight's ceremony. We'd like to congratulate all three teams for their efforts in making it to the World Finals, and no matter the final results we are sure that this will be an experience that they will never forget.  If you (or your kids) want to get involved in F1 in Schools next year, we encourage you to visit the REA F1 in Schools website for more information.
