Title Determination of soot refractive index as a function of height in an inverse diffusion flame
Date 2007
Description With the scope of combustion diagnostics increasing, it is becoming ever more important for some of the more basic physical properties of soot to be addressed. Soot refractive index values were obtained as a function of height in a benzene inverse diffusion flame (IDF). The IDF was chosen for ease in extraction of soot particles, with minimal flame interference. Refractive index measurements were obtained in the infrared with a Kramers-Kronig transformation of diffuse reflectance from a Fourier Transform Infrared Spectrometer (FTIR), and ellipsometry measurements extended the range of index values into the visible. A comparison of results from previous investigators indicates refractive index varies as a function of fuel type, residence time (height), wavelength and temperature.
