Optical Emission Tomography of Non-axisymmetric, Laminar, Premixed Flames

摘要

Optical emission tomography of flames has recently beendemonstrated as a practical experimental technique for determiningthe instantaneous position of a 3D flame surface. Inthis paper, optical emission tomography is applied to steady andforced, non-axisymmetric, premixed, laminar flames. An experimentalset-up involving a single camera and a rotatable flameholder allows camera images from an arbitrary number of directionsto be obtained. The 3D flame surface is identified andthe spatial and temporal resolution of the results is discussed.The dependence of the reconstruction on the number of viewsis investigated.
