The HTPV is a flow through chamber using electric heating at high pressures capable of obtaining 1000 K and 150 bar at steady state in the test section. The objective of these tests is to validate and examine the measurements performed in this flow-through facility as compared to tests in a constant volume, pre-combustion chamber that are reported through the Engine Combustion Network being organized by Sandia National Labs (www.sandia.gov/ecn). Thus, the experimental conditions are those of Spray A of the Engine Combustion Network, and the facility was measured to meet those conditions within ~2% temperature and 1% on pressure. The temperature homogeneity and injector temperature have also been characterized. Spray and combustion measurements have been performed for liquid penetration, vapor penetration, and combustion liftoff length. The combusting fuel jet was analyzed by examining the filtered light emission from the combustion region with high speed cameras, with spectral filters looking at the OH chemiluminescence, CH chemiluminescence, and soot luminosity. Mie scattering from the liquid droplets was also measured. The results of these measurements compare well with measurements from other chambers, and differences for those measurements will be discussed.} }
