In turbulent combustion, such as that encountered in a gas-turbine engine, regions of locally high strain may cause a flame hole to develop in the reaction sheet. The edges of the hole caused by this local extinction point can be characterized as forwardly propagating if they move in the direction of unburned fuel and air or negatively propagating if they(More)
Three-dimensional (3D) images of flame emission are reported using a single direction of optical access. A Cassegrain system was designed with narrow depth of field. Images from this system are dominated by emission from the focused object plane with defocused contributions from out-of-plane structures. Translation of one mirror in the system allows for(More)
