This LaVision High-Speed 2D PIV System is employed to acquire comprehensive insights into the swash flows generated by a train of solitary waves and the concurrent turbulence structure. This system conducts two-dimensional velocity measurements utilising a 100-Hz high-speed particle image velocimetry (HSPIV) technique.
 
LaVision’s flow field imaging laser systems, known as FlowMaster, leverage cutting-edge Particle Image Velocimetry (PIV) techniques.

The study of turbulent combustion greatly hinges on flow-chemistry interactions. Our high-speed laser imaging technology, which incorporates both PIV and OH-PLIF simultaneously within the same light sheet plane, enables the exploration of these intricate flow-flame interactions inherent in phenomena like ignition and flame extinction processes. LaVision’s laser imaging framework uniquely facilitates such concurrent PIV and PLIF measurements, supported by our established FlowMaster and FlameMaster systems, both utilising the DaVis platform for synchronised image capture and data processing.

FlameMaster Setup & Installation

Testing of the measurement of flame temperature using FlameMaster
Calibration setup using a filament lamp

LaVision’s Two-Color Pyrometry setup provides a robust system for temperature measurements. It demonstrates the precise measurement of flame temperature, showcasing the system’s accuracy and capability. Additionally, the calibration process is conducted using a filament lamp, ensuring the system’s reliability and accuracy through meticulous calibration procedures.

LaVision Flamemaster Software

The FlameMaster inspex imaging systems apply flame emission spectroscopy to combustion processes.

​The flame emission (chemiluminescence) of flame radicals like OH*, CH*, C2* is used to e.g. visualise the reaction zone or to monitor flame stoichiometry via emission ratios of such radicals. 2-colour pyrometry (blackbody radiation) is used to measure temperature fields in sooty flames.
