This page contains liquid/vapor data under six different ECN Spray G (AV67-028) conditions (G1, G2, G3, G2-cold, G3-cold, and G3-double).
Vapor penetration measurements from Manin 2015 were previously posted to the ECN primary Spray G dataset, but were found to be in error. This data can be found here, but we do not recommend their use.
Data analyzed by high-speed extinction and schlieren imaging with a shutter speed of 67,200fps and a resolution of 512 by 512 (extinction:0.1908mm/pixel, schlieren: 0.213mm/pixel).
Liquid (liquid_data_2e-3_thr and liquid_data_2e-4_thr)/vapor (vapor_data) penetration and width data for iso-octane (ic8) and 3-component surrogate fuel (E00 n-pentane 36%, iso-octane 46%, n-undecane 18% (v/v)) is available.
Liquid was characterized by projected liquid volume (PLV) threshold of 0.2e-3 mm^3liquid/mm^2 and 2e-3 mm^3liquid/mm^2.
Local (not projected) liquid volume fraction (LVF) at 12 different planes (YZ (X=0), XY (Z=2, 5, 8, 10, 12, 15, 20, 30, 40, 50, 60mm)) enabled by Sandia 3D-CT is available.
In-chamber temperature data under G1 condition is available here.
