Multidimensional tomographic diagnostics
This research aims at obtaining three-dimensional (3D) imaging measurements in turbulent flames at kHz rate based on tomographic chemiluminescence (TC) and other tomographic techniques. Such measurement capability has been long desired to resolve the inherent 3D spatial structures and temporal dynamics of turbulent flames. In this work, multiple high speed cameras were employed to simultaneously record projection measurements of chemiluminescence emissions of turbulent flames and flows at multi-kHz. These projection measurements were then used as the inputs for a tomography inversion algorithm to yield the 3D instantaneous spatial structures of the flames and flows in a measurement region of ~10×10×10 cm. |
