Post-shock Sampling of Shock-heated Hydrocarbon Fuels
Abstract
The objective of this STIR proposal is to implement an extractive sampling method to make comparative measuremen ts of in-situ optical measurements to study the potential of post-shock sampling of shock-heated hydrornrbon foe ls. This wil l provide an opportunity to augment the current in-situ optical sensing of species in the reflected shock-wave experiments. This will extend measurements to those species currently inaccessible to optical methods (e.g. ethylene, methane, acetylene). The objective will be achieved by installing and implementing an extractive gas-sampling system into the existing Stanford shock-tube facility. The sampling will include gas chromatograpl1y and/or mass spectroscopy. Measurements will be compared to in-situ optical mea urcments. The method is designed to allow measurement of long-time values of species at relatively long shock-hi be test times. This will allow observation of fuel cracking patterns currently inaccessible via optical methods. The resulting data will aid greatly in understm1ding fuel kinetics and ignition at high pressure.
