Abstract
Optical emission tomography of flames has recently been demonstrated as a practical experimental technique for determining the instantaneous position of a 3D flame surface. In this paper, optical emission tomography is applied to steady and forced, non-axisymmetric, premixed, laminar flames. An experimental set-up involving a single camera and a rotatable flame holder allows camera images from an arbitrary number of directions to be obtained. The 3D flame surface is identified and the spatial and temporal resolution of the results is discussed. The dependence of the reconstruction on the number of views is investigated.
