Investigation of Combustion Process Using Fiber Optics.
Abstract
This technical report describes the results of a 12-month program to design, build, and test a fiber optic viewing device (fiberscope) on a high pressure gas turbine combustor rig. High speed motion picture photography along with video tapings were made of the combustor flame with the fiberscope. With the high speed photography the turbulent flame motion could be followed in some detail. Visible wavelength spectra were taken of the flame emission through the fiberscope and analysis indicates that a mean flame temperature can be measured. The fluctuation frequency spectrum of the flame was also observed with a fast fourier transform analyzer, and the possibility of coupling with acoustic resonances was indicated. In addition, the fuel spray was illuminated with laser light from the fiberscope probe and contour plots were made of a sequence of frames from the movie film. The combustor viewing probe may be used as an important aid in future combustion design and to help determine causes of various failure modes of combustor liners. (Author)
