LaVision: Full-scale Ring-of-Fire PIV measurements in the Catesby-Tunnel

Under the motto "Innovation Meets Legacy", the aerodynamic behavior of an iconic vehicle was examined.

LaVision engineers carried out a very special test in the fantastic Catesby-Tunnel: The longest and most repeatable indoor test facility in the world. Once a railway tunnel, it has been converted into a vehicle test facility providing incredible repeatability and accuracy. The tunnel was closed to trains in the 1960s which is the same time when the Jaguar E-type was created. The LaVision team set up a PIV Ring-of-Fire system comprising Photron high-speed cameras, a Litron LDY laser, and filled the test section area with helium-filled soap bubbles (HFSB).

LaVision published a paper about the novel Object-aware Lagrangian Particle Tracking (OA-LPT) scheme in the Measurement Science and Technology journal

This technique provides a solution to the practical problem, which sometimes occurs when measuring flows around objects.

The measurement of flows around objects such as cars, airfoils and maritime structures often poses major challenges for optical flow diagnostics methods such as Tomo-PIV or Lagrangian Particle Tracking (LPT)/Shake-the-Box (STB) within the measurement fields. Also, many flow reconstruction algorithms simply do not have the capabilities of incorporating such object information.

LaVision's active partnership in the successful European project NIFTI (Non-Intrusive Flow distortion measurements within a Turbofan Intake)

NIFTI (Non-Intrusive Flow distortion measurements within a Turbofan Intake) is a joint project launched under Grant Agreement 864911 of the European Union’s Horizon 2020 research and innovation program. It aims to advance the state of the art in non-intrusive inlet flow distortion measurements for modern, civil aero-engines.

We describe where the various approaches are applicable and how to carry them out. This includes a description of a new two-step calibration approach applicable for very large measurement objects, and a new co-ordinate transform option.

Shake-the-Box - Overview and recent developments

This webinar will provide an overview of Shake-the-Box (STB), our state-of-the-art, 3D Lagrangian particle tracking algorithm. The experimental methodology will be outlined, including the calibration, image pre-processing, Volume-Self-Calibration (VSC), particle tracking and conversion-to-grid steps, both by binning and data assimilation. Exemplary applications of STB from our diverse range of customers and research partners will be presented to demonstrate the efficacy and versatility of the technique.

Investigation of stochastics during ignition processes at the Physikalisch-Technische Bundesanstalt Braunschweig with laser diagnostic system from LaVision

Existing standards in the field of explosion protection are based to a large extent on empirical knowledge and less on scientific principles. Ignition processes must therefore be better understood. The ignition of explosive gas mixtures by electrical discharges at low energy behaves stochastically, both qualitatively (sometimes the mixture ignites, sometimes not) and quantitatively. The flame propagation is different for each repetition of the experiment.

Experimental study of protective masks using LaVision equipment

Professor Christian J. Kähler and his assistant Dr. Rainer Hain at The Institute of Fluid Mechanics and Aerodynamics at the University of the Federal Armed Forces in Munich, conducted detailed flow experiments to examine the effectiveness of face masks and various filter materials from a fluid mechanics point of view.

The aim of the study was to explore to what extent the currently much-discussed safety measures, such as social distancing or the use of face masks, are effective against a droplet infection with the Corona-virus SARS-CoV-2.

Their intriguing results using the Particle Image Velocimetry (PIV) measurement technique are shown in this video.

Face masks are reducing COVID-19 infection risk: See how with LaVision Background Oriented Schlieren Imaging

The primary way of person-to-person corona virus transmission is via aerosols or small droplets created by breathing, sneezing or coughing. The reach of exhaled air can be effectively reduced using a face mask as shown in the video. A simple Schlieren imaging technique is applied to visualize the air flow caused by a person breathing and coughing. Using a face mask the exhaled air flow is blocked reducing effectively the risk of infection. Also nicely shown is the heat transfer from the body to the cooler ambient air. More information about the LaVision Background Oriented Schlieren imaging technique is given here.
