COMBUSTION DIAGNOSTICS Advanced Optical Measurement Solutions

Velocity characterisation of a spray combustion facility using Stereoscopic PIV, National Institute of Standards and Technology, Gaithersburg, US.

Combustion processes are used in many modern technologies such as electrical power production, heating, and automotive and aircraft/space-shuttle propulsion. Laser diagnostic techniques can help improve our understanding of combustion processes and thus contribute to reducing the carbon footprint of mankind. Combustion Diagnostic Systems Dantec Dynamics offers a full range of combustion diagnostics measurement solutions that integrate advanced timing devices, state-of-the-art lasers, the latest camera and image intensifier technology with image acquisition and data analysis software. This makes...

Detailed Investigations of Molecular Species using L Spectral filter Image intensifier Nd:YAG laser Rail with Light sheet optics Combustion Radicals and Products Measurements by LIF Laser-Induced Fluorescence (LIF) is the most powerful technique available today for experimental diagnostics of combustion processes. Based on the physics of interaction between light and individual molecules, the technique allows for species-selective measurements with high sensitivity. Dantec Dynamics' highly advanced and flexible system for combustion LIF is capable of measuring a wide range of combustion radicals...

An overview showing the principle of Dantec Dynamics' combustion diagnostic systems. The system shown here includes an advanced and flexible tuneable dye laser used for measuring a wide range of combustion species. Fuel Visualisation by Tracer-LIF By adding a fluorescent tracer species (e.g. acetone) to a non-fluorescent fuel, you can carry out diagnostics studies of the combustion as well as pre-combustion process. Dantec Dynamics' powerful yet easy-to-use tracer-LIF dedicated system enables you to study a wide range of applications, from open flames to internal combustion engines, for properties...

Monitor all the Different Aspects of the Combustion Soot Diagnostics by LII Dantec Dynamics' system for Laser-Induced Incandescence (LII) is a solution for quantitative determination of soot volume fraction. The LII software provides access to advanced image calibration and analysis methods, as well as non-linear signal compensation algorithms for greater accuracy when working with sooty processes. The system includes features such as: • Numerical methods for calibrating line-of-sight, LII decay time and gas composition dependence of the LII signals • User-friendly image processing interface...

OH* chemiluminescence from a slightly turbulent atmospheric flame at around 308 nm with exposure times of 100 µs, 1 ms and 10 ms respectively. Temperature Mapping by Rayleigh Scattering Light that is elastically scattered by molecules, Rayleigh scattering, is directly related to the density of the molecules. This can in turn be converted to temperature, making Rayleigh scattering a suitable tool for 2D thermometry in combustion research. Chemiluminescence Imaging Chemiluminescence imaging can be a valuable diagnostics tool for combustion processes. The technique relies on detection of the naturally...
