Focus on Combustion - 2

Energy Challenges of Today Developing industries and quickly increasing markets worldwide are continuously demanding an increased primary energy supply, reliable domestic production and flexible public transportation. Even though alternative technologies are a growing market and will gain relevance, conventional power generation from combustion will continue to hold a strong share of the energy mix for the next decades (see „world energy outlook" below). The diversity of fuels for power and heat generation with the stronger impact of renewable sources has been massively extended....

Optical Measurement Solutions Advanced Combustion Diagnostics Due to their non-intrusive nature, optical diagnostics offer unique capabilities for in-situ multi-parameter reactive flow field measurements even in the harsh environment of practical combustion systems. These can not be achieved using conventional, i.e. non-optical probe techniques. Optical diagnostics contribute significantly to the reduction of combustion generated pollution, particularly the greenhouse gases CO2, CH4 and H2O. LaVision‘s Expertise LaVision has over 25 years of expertise and experience in the field of...

Insight into Reaction Chemistry Energy Transformation LaVision offers diagnostic solutions for the detection of reactive species. These systems can characterize the conditions inside the reaction zone of laminar and turbulent flames. The location of initial flame kernels and precursor species is identified via species selective detection of the chemiluminescence. Advanced diagnostics such as LIF enable instantaneous 2D imaging of important intermediate species in reaction kinetics like H2CO, CH and OH. LaVision’s diagnostic tools furthermore utilize processes like spontaneous Raman...

High-Speed Combustion Imaging Time-resolved (Laser) Imaging Most mixing and combustion phenomena are highly turbulent processes where diagnostic tools require high spatial and temporal resolution. Truly time-resolved laser imaging requires repetition rates in the kHz-range to visualize the development of unsteady or statistical phenomena such as flame vibrations. These diagnostic tools have become available with the development of powerful laser sources and sensitive detection units, like intensified CMOS cameras. 4modular image intensifiers: The modular design adds UV-sensitivity and short...
