Abstract
"Due to the growing concerns that particulate matter (PM) have on health and the environment, there is a need to include mass and number non-volatile PM measurements to current jet engine certification. This thesis looks at the necessary work required to help produce recommendations and perform background research to aid in the creation of an improved Aerospace Recommended Practice (ARP) (by the SAE E-31 Committee). This work addressed the following issues. The investigation began in the Missouri S&T Center of Excellence for Aerospace Particulate Emissions Reduction Research (COE) laboratory with an examination of the jet engine surrogate used, the miniCAST, as well as integrating it into the COE's PM measurement system. A clean PM sample line was aged by running a PM source through it until a steady state signal was measured by the instruments in order to make a recommended procedure for line conditioning as well as reconditioning. Several eductors were studied for their performance characteristics and compared against desired characteristics, which suggested a need to include a pressure relief valve to cap the sample pressure at the eductor entrance. A volatile particle remover (VPR) was studied for penetration and ability to remove volatile material. A prototype E-31 system was setup at the second alternative aviation fuel experiment (AAFEX II), which provided a direct comparison of probe tip dilution and downstream dilution and found comparable results when line loss was taken into account. Also performed at AAFEX II was a study that compared measured sample line penetration with theoretical calculations finding that theoretical calculations were an accurate alternative of measuring line loss. Two PM sampling systems were setup at an ARP demonstration and both system had similar results for both number and mass measurement. An instrument comparison was also performed that included an examination of condensation particle counter (CPC) cutoff size. It was also determined that a VPR was necessary to ensure that number instrument devices were only measuring non-volatile PM."--Abstract, page iii.
