| Abstract: | Optical pyrometers that operate in gas turbine aeroengines are exposed to contaminate particulates from the atmosphere of the operating environment, which can deposit on the instrument's lens and thus foul the system's optics. This particle deposition process results in the attenuation of the thermal radiation signal, from the pyrometer's measurement target, due to transmission losses through the layer of deposits on the lens. A purge air system is therefore employed to minimize the level of optical contamination. This article outlines the generic air-purging configurations and highlights their operation through providing both flow field and particle trajectory analyses via computational fluid dynamics (CFD) in order to provide an evaluation of their operating performance.
