Title
DualPump CARS Measurements in CounterFlow Flames using OPO,Used
Delivery time: 8-12 business days (International)
A new laser system has been developed to measure temperature and major species concentrations using dualpump N2CO2 coherent antiStokes Raman scattering (CARS). The second harmonic output from an injectionseeded Nd:YAG laser was used as one of the narrowband pump beams.The second narrowband pump beam was generated from an optical parametric oscillator injectionseeded at the idler wavelength using an external cavity diode laser.A broadband dye laser produced the Stokes beam. The three beams were focused between two opposing nozzles of a counterflow burner facility to measure temperature and major species concentrations in a variety of partially premixed and nonpremixed methane and hydrogen flames at atmospheric pressure. Sandia CARSFT code was used to conduct a least squares fit process. Temperature was obtained from fitting only the nitrogen spectrum at every measurement location. In general, excellent agreement was observed between measured temperature profiles and those predicted using an opposedflow flame code in conjunction with detailed chemistry for methane flames.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
