Conference Description

Non-intrusive laser diagnostics for the spatially and temporally resolved measurement of temperature, chemical composition, and flow parameters have emerged over the last few decades as major tools for the study of both fundamental and applied combustion science. Many of the important advances in the field can be attributed to the discussions and ideas emanating from this meeting. This conference, originating in 1981 and held biennially, focuses on laser-based methods for measurement of both macroscopic parameters and the underlying microscale physical and chemical processes. Applications are discussed primarily to elucidate new chemical and physical issues and/or interferences that need to be addressed to improve the accuracy and precision of the various diagnostic approaches or to challenge the community of diagnosticians to invent new measurement techniques. Combustion environments present special challenges to the optical diagnostics community as they address measurements relevant to turbulence/chemistry interactions important in practical combustion systems as well as fundamental chemical reactions in stable laboratory flames. The diagnostics considered may be generally classed as being incoherent, where the signals are radiated somewhat isotropically, or coherent, where the signals are generated in a directed, beam-like fashion. Both of the foregoing may employ either electronic or Raman resonance enhancement or a combination of both. Electronic resonant techniques generally permit detection of constituents at trace levels, i.e., parts per million level, such as important reaction intermediates and trace pollutants. Raman based approaches on the other hand are limited in sensitivity to the major constituents, (mole fractions of 10-3 or higher) such as nitrogen or oxygen. Prominent incoherent approaches include laser induced fluorescence (LIF), spontaneous Raman scattering, Rayleigh scattering, laser induced incandescence, and molecular flow tagging and their two- and three-dimensional imaging variants. Coherent approaches include coherent anti-Stokes Raman scattering (CARS), degenerate four wave mixing (DFWM), polarization spectroscopy (PS), laser induced grating spectroscopy (LIGS) and laser-based absorption spectroscopy. Spectroscopic modelling and validation are key elements to extract accurate parameter measurements and discussions focusing on key energy transfer processes, collisional models, lineshapes and widths feature prominently. The properties and behaviour of lasers, optical arrangements and techniques, spectrally-selective and dispersive instruments and detectors are also important determinants of successful measurements and are discussed in detail. Recent developments in the conference have highlighted the application of techniques developed for combustion research that find application in other areas such as biological or plasma processes. Hot topics in the field are featured in a special session selected from contributed posters to highlight the most recent advances and future directions.

What is a GRC? Gordon Research Conferences (GRC) are 5-day meetings that bring scientists together from around the world to present and discuss unpublished research with other leaders in their field.

Related Conference

This Gordon Research Conference (GRC) series is related to the "Laser Diagnostics in Combustion" Gordon Research Seminar (GRS) series. Although a related GRS will typically be scheduled in conjunction with its parent GRC each time it meets, that may not always be the case. Refer to the individual meetings in the Meeting History section below for more details. For more information about the associated Gordon Research Seminar (GRS) series, click here.

What is a GRS? Gordon Research Seminars (GRS) are 2-day meetings that bring graduate students and post-docs together to discuss their cutting edge research among peers and mentors. Each GRS immediately precedes an associated Gordon Research Conference (GRC), and topics addressed at the GRS relate closely to the GRC.
