Planar laser-induced fluorescence (PLIF) is an optical diagnostic technique widely used in fluid and gas applications. PLIF has proven to be a valuable tool for flow visualization as well as for quantitative whole-field measurements of scalars such as concentration and temperature in liquid and concentration in gaseous flows. Applications can be found in process engineering, biomedical engineering, and fluid dynamics research.
Mixing and heat transfer studies in liquid flows by LIF
With Dantec Dynamics’ planar LIF 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 studies in gas phase flows by tracer-LIF
By adding a fluorescent tracer species (e.g. acetone) to a non-fluorescent fuel or gas, visualization of the gas phase mixing as well as quantitative concentration measurements can be made by means of LIF. One common application is fuel visualization in development of combustion engines, where LIF allows for diagnostics of the pre-combustion as well as the combustion process to be made.
Dantec Dynamics’ powerful yet easy-to-use system dedicated for gas phase tracer-LIF enables investigations of properties such as:
- Fuel distribution
- Ignition phenomena
- Fuel injection behavior
- Gas phase mixing studies
