Abstract

In this work, the temperature field of a methane-air non-premixed coflow flame obtained via numerical simulation is used to induce radiance emission from the surface of a thin filament directly exposed to the flame. The radiance signal is subsequently processed through a digital camera simulation to generate synthetic radiance photographic images. Results from the theoretical analysis are validated against images captured from a corresponding experiment, where the light emitted by a thin filament in contact with a non-premixed coflow system is obtained using an automated imaging system at selected heights along the axis of the flame.
