abstract = "Quantitative imaging of radiation intensity (QIRI) is a method of investigating temporally and spatially resolved radiation from species and particulates in turbulent flames. The current study reports quantitative images of radiation intensity from a turbulent sooting ethylene flame that matches the Reynolds number (15,200) of a standard flame from the International Workshop on Measurement and Computation of Turbulent Non-premixed Flames. A calibrated high-speed infrared camera with three band-pass filters was used to acquire images of radiation intensity in wavelengths corresponding to carbon dioxide, water vapor, and soot. The luminous flame measurements show thin radiating structures corresponding to soot layers and higher mean and fluctuating radiation intensities compared to quantitative images of radiation intensity from a non-sooting flame. A technique is also presented demonstrating computed images of radiation intensity of a turbulent luminous flame by utilizing a Large Eddy Simulation (LES) and a narrowband radiation intensity model. Preliminary comparisons are made between the experimental and initial computational images of radiation intensity in order to prompt improvements in turbulent sooting flame computational models.",
