Case study: Industrial flow optimization with ProCap

/in ,

Task

Our customer builds and operates a wide range of monitoring equipment such as radio antennas that are required to operate reliably even in adverse weather conditions. To do so, the antennas are heated and include a fan to prevent the accumulation of snow on the surface of the antenna. During heavy snowfall however, it was repeatedly observed that the fan was not able to remove the snow which caused the signal quality to deteriorate.

Our task was to optimize the snow removal efficiency without changing the instrument too much. The solution should also be applicable to already installed systems.

3D Flow Field Measurement System on Cable Cars

Who would have thought that the ventilation of cable car cabins would suddenly become important? We put ProCap through its paces with collecting 3D flow data in broad daylight in a moving cable car. And were amazed at how easy it was. Thanks to Dr. Ivan Lunati from EMPA for giving us the opportunity!

Here the press release by EMPA on this joint work. The cooperation led to a publication in scientific journal you can find HERE.

ProCap: Live demonstration for performance cycling

The Flander’s Bike Valley wind tunnel at the heart of the ‘classics’ in bicycle racing was the ideal location to introduce a new measurement method to a very aero-oriented sport. And so, on November 25th, leading exponents from the sport found their way to the “silicon valley” of cycling to experience hands-on how much real-time 3D flow visualization can add to wind tunnel testing. We would like to thank everybody present that day and especially the people from Bike Valley for the avid discussions, their feedback and for sharing our excitement of having more than a drag coefficient to work with!

Caution: This is NOT CFD, but full size measurement data!

The test setup was a full-sized road racing bike including rider-dummy complete with helmet and cycling wear. We did not focus on a specific area during the tests but tried to show what the people present were interested most in. This approach worked beautifully as in front of the big visualization monitor the discussion and interpretation of the flow started immediately with the first data points coming in. During the measurement, the focus could be shifted to different areas by guiding the operator holding the probe or by zooming in on a specific detail. A very efficient optimization and solution-finding process was set in motion right with the start of a measurement!

This is exactly what ProCap is meant to achieve and it was truly rewarding to see it happen immediately. The demonstration showed us that with this intuitive and flexible approach one can get the most out of this type of wind tunnel testing. We are looking forward to see the results of improved aerodynamic testing hitting the cycling track!
