Planar Laser-Induced Fluorescence in liquid phase flows (PLIF) is an optical diagnostic technique widely used in fluid applications.

Laser-Induced Fluorescence in liquid phase flows has proven to be a valuable tool for flow visualization as well as for quantitative whole-field measurements of concentration and temperature in liquid flows. Applications can be found in process engineering, biomedical engineering, and fluid dynamics research.

Mixing and heat transfer studies in liquid flows by Laser-Induced Fluorescence

With Dantec Dynamics’ planar Laser-Induced Fluorescence solutions, quantitative information can be obtained in many applications, including:

  • Mixing performance of chemical processes.
  • Interaction between large-scale and smaller-scale in turbulent mixing.
  • Dispersion of pollutants in model ocean systems.
  • Heat transfer phenomena in heat exchangers, pumps and other devices for improvement of apparatus performance and equipment design.
  • Temperature distribution in fluids of engineering interests such as foodstuffs and paints.

Mixing in Liquid by LIF



  • Non-intrusive technology.
  • Quantitative, precise and accurate measurements of concentration or temperature fields.
  • In combination with velocity measurements, transport properties (e.g. Reynolds flux, turbulent diffusion coefficients and other parameters) are made experimentally available.
