Multiparameter spatio-thermochemical probing of flame–wall interactions advanced with coherent Raman imaging
Abstract
Ultrabroadband coherent anti-Stokes Ra man spectroscopy (CARS) has been developed for one -dimensional imaging oftemperature and major species distributions simultaneously in the near-wall region of amethane/air flame supported on aside-wall-quenching (SWQ) burner. Automatic temporal and spatial overlap of the ~7 femtosecond pump and Stokes pulsesis achieved utilizing a two-beam CARS phase-matching scheme, and the crossed ~75 picosecond probe beamprovide sexcellent spatial sectioning of the probed location. Concurrent detection of N<sub>2</sub>, O<sub>2</sub>, H<sub>2</sub>, CO,CO<sub>2</sub>, and CH<sub>4</sub> is demonstrated while high-fidelityflame thermometry is assessed from the N<sub>2</sub> pure rotational S-branch in a one-dimensional -CARS imaging configuration. Amethane/air premixed flame at lean, stoichiometric, and rich conditions ( Φ = 0.83, 1.0 , and 1.2) and Reynolds number = 5,000is probed as it quenches against a cooled steel side- wall parallel to the flow providing a persistentflame-wall interaction. Here, an imaging resolution of better than 40 μm is achieved across the field -of-view, thus allowingthermochemical states (temperature and major species) of the thermal boundary layer to be resolvedto within ~30 μm of the interface.
