3D flame topography obtained by tomographic chemiluminescence with direct comparison to planar Mie scattering measurements

Abstract: This work reports the measurements of 3D flame topography using tomographic chemiluminescence and its validation by direct comparison against planar Mie scattering measurements. Tomographic measurements of the 3D topography of various well-controlled laboratory flames were performed using projections measured by seven cameras, and a simultaneous Mie scattering measurement was performed to measure a 2D cross section of the 3D flame topography. The tomographic measurements were based on chemiluminescence emissio… Show more

“…The side view shown in Figure 4f is unable to reveal the 3D structure of the flame. Besides such visual comparison, the 3D tomographic reconstruction has also been validated via other methods in our past work, for both numerical simulations [27] to controlled flames [42].…”

“…Tomography has gained considerable attention in recent years. The chemiluminescence is frequently utilized as the marker for the flame front and quanti ty to be reconstructed [12][13][14][15][16][17][18][19]. Either contributions from all excited radicals are collected or filters, centered on the OH* or CH* emission, are employed.…”

“…CT of flame luminescence has been conducted with a single camera to obtain the mean or phaseaveraged flame shape [13,14,19]. However, to obtain an instantaneous flame surface, several simultaneous views are required; for example, seven and eight cameras have been used in [18] and [15], respectively. Alternatively, five cameras plus mirrors where used in [12] to project two views onto each camera sensor and hence obtain ten views.…”
