Multiple recent innovations were displayed at the LaVision booth. The capabilities of Background-oriented Schlieren can be extended to 3D. Digital Tomographic Schlieren gives access to time-resolved quantitative 3D flow imaging, for instance of temperatures in flames.

Particle-based 3D measurements are performed with Tomographic PIV and also with Shake-the-Box. The capabilities are largely extended with LaVision’s 3D camera MiniShaker. With Helium-filled soap bubbles scattering more than 10000 times brighter than common aerosol seeding particles and with robotic support, the system is ideal for large-scale measurements in wind tunnels.

For a first impression of the flow topology particle tracks are great but for a detailed analysis data on a regular grid, like in Tomographic PIV, is often preferable. To this, LaVision presented VIC#, a novel method based on data assimilation resulting in an unsurpassed grid resolution.
Also direct retrieval of pressure data from data on a regular grid is now possible. Pressure from PIV with LaVision’s 4D solver offers access to pressure data from PIV measurements in 2D and 3D, time-averaged and time-resolved.

The information was complemented by multiple exhibits at the booth including a MiniShaker L camera. A live experiment showed its application for volumetric water flow measurements together with the new DaVis 10 software package. LaVision’s high-power LED-Flashlight 300, a cost-effective and easy to use alternative to high-speed lasers for many applications, was used for the illumination. Also an aerodymically-optimized seeder for Helium-filled Soap Bubbles was displayed. A MiniShaker Aero mounted to a robotic arm demonstrated its high flexibility for volumetric air flow measurements.

The LaVision team thanks all visitors for their lively interest and the organizers for their commitment for a successful symposium.
