Aerodynamic Research by
Computational Fluid Dynamics
In 1998, Dr Adrian Reynard founded Advantage CFD
Ltd in order to explore aero solutions that were not easily researched
in either wind tunnel development or full scale data acquisition
on board the vehicle.
Dr Robert Lewis was recruited to lead this campaign
and he immediately discovered that CFD was not only useful for these
discreet gains, but also a vital tool in the aerodynamicists toolbox
for validation and thought provocation.
One of the biggest appreciators was the Honda
Racing F1 Team which is also co-owned by Dr Adrian Reynard. By 2002
the A-CFD team had grown to over 20 staff and as well as many commercial
client applications throughout the transportation industry, Honda
Racing had also grown quite dependent for its valuable contribution
to the Honda Racing F1 car development. So Honda Racing bought A-CFD
Reynard firmly believes that this is a technology of the future.
He addressed the 5th MIRA Vehicle Aerodynamic Conference in October
2004 and featured some of the award winning CFD movies that he had
In the side bar are some samples of the
movies. The colours can represent pressures or velocities. These
are not just pretty videos since the true geometry of the car is
created by CAD and mesh first so that any position can be interrogated
for real data. Real-time results can be evaluated an a configuration
change can be much faster than by other data-collection methods.
The optimum design can therefore be solved very rapidly.
In 2010 the Auto Research Center LLC in Indianapolis strengthened its C.F.D. facility to 84 processor cores. This PowerWulf computer engine allows clusters of processors to solve large problems.
