| Abstract | Nano-sized titanium dioxide (TiO2) particles are widely used in industry. In this study, we investigate how laser-based techniques may be candidates for non-intrusive measurements of TiO2 nanoparticles in flame. The TiO2 nanoparticles are strong optical absorbers in the ultraviolet (UV) region, thus extinction/scattering and laser induced incandescence (LII) techniques can be used to evaluate both the volume concentration and the size of TiO2 nanoparticles. The theory of light absorption and scattering of TiO2 nanoparticles is analysed, and a preliminary heat transfer model of time-resolved LII (TiRe-LII) for TiO2 nanoparticles sizing is also presented. |
