What is it about?

We have developed a great extension to the well known 3D-PTV experimental method. We can measure Lagrangian turbulent statistics using four synchronised high speed cameras and a special FPGA cards that can analyse motion of particles as the fly in the wind tunnel

Why is it important?

From now and on researchers and engineers could measure things they have only being imagined before. You car aerodynamics, spread of air pollutants and hundreds of other turbulent flow problems are more accessible and easily presentable. We can cut down the research work and time-to-insight from months to one day.


In the future, we will be able to show velocity of the moving air at the moment it changes. We will be able to provide measurable parameters to the control engineers to change the flow around bodies and reduce drag, create lift, understand physics of flows.
