Velocite expands the bicycle aerodynamics service with a low speed wind tunnel

A new and very exciting development is our new ability to add wind tunnel testing and verification to our existing industry leading computational fluid dynamics (CFD) simulation capability.

For several years already we have been performing advanced CFD aerodynamics simulations for our own use, and for other companies. The main differentiator between our CFD capability and what is already offered in the market is our ability to use actual product geometry without having to simplify it, being able to simulate at a much higher resolution, and not having to predetermine the outcome – we do not need to tell our CFD software what to expect and thus potentially influence the outcome.

Similarly the wind tunnel that we are using, and which is based at the Flanders Bike Valley in Belgium (next to our office actually) is not a general purpose wind tunnel, and it is not a wind tunnel that was designed for testing cars or airplanes. It was designed and instrumented to test bicycles and bicycle scale products under low air speed conditions. This is important because not only are the flow conditions suited to studying bicycles and bicycle related products, but the measurement system is designed to measure the slightest differences in force. General purpose and automotive sensors are generally not able to register the small differences in force, but which describe the aerodynamic performance of bicycles and bike parts.


Another special feature of the Flanders Bike Valley wind tunnel is the ability to fully visualize the airflow thanks to the laser based particle image velocimetry (PIV) system

Lastly, we also have access to a full size, articulated dummy of a rider that we can use for R&D purposes, and of course the test platform is capable of securely supporting an actual rider so we are capable of also providing aerodynamic fitting services as used by the Belgian national track racing team in preparation for the 2016 Olympic games.
