Abstract
In present study, the instantaneous three-dimensional distribution of the chemiluminescence light emission image of turbulent premixed "blue" flame is captured as a fuel consumption rate distribution by a newly proposed technique; "instantaneous three-dimensional scanless computerized tomography (3D-CT) technique" with a custom-made multi (40)-lens camera. The results for a propane-air fuel-rich-premixed turbulent flame show that the flame front is observed to be a thin wrinkled luminous region of 0.6mm in thickness and that the cusps observed in horizontal cross-sections correspond to ridges of the three-dimensional flame front. It is also found that the luminosity distribution is quenched along the ridges. The maximum value of local fuel consumption rate is estimated to be 0.23 g/s/cm^3.
