Description:
Synchrotron x-radiography and a fast x-ray detector were used to record the time evolution of the transient fuel sprays from a high-pressure injector. A succession of 5.1-microsecond radiographs captured the propagation of the spray-induced shock waves in a gaseous medium and revealed the complex nature of the spray hydrodynamics. The monochromatic x-radiographs also allow quantitative analysis of the shock waves that has been difficult if not impossible with optical imaging. Under injection conditions similar to those found in operating engines, the fuel jets can exceed supersonic speeds and result in gaseous shock waves.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉MacPhee, Andrew G -- Tate, Mark W -- Powell, Christopher F -- Yue, Yong -- Renzi, Matthew J -- Ercan, Alper -- Narayanan, Suresh -- Fontes, Ernest -- Walther, Jochen -- Schaller, Johannes -- Gruner, Sol M -- Wang, Jin -- DMR-9713424/PHS HHS/ -- New York, N.Y. -- Science. 2002 Feb 15;295(5558):1261-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Advanced Photon Source and, Energy System Division, Argonne National Laboratory, Argonne, IL 60439, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11847333" target="_blank"〉PubMed〈/a〉
