Abstract:A set of scaling factors derived from the conservation equations effectively collapsed fuel jet penetration measurements under both motoring and stationary piston conditions. The scaling factors are based on the pseudo diameter of the jet, which is the diameter of an equivalent sonic jet expanded to match the in-cylinder conditions. The penetration of the fuel jets compared favorably to a two-region vortex ball model of jet penetration. The CARS measurements show large fluctuations in fuel concentration on a shot-to-shot basis, which are consistent with the large-scale mixing structures evident in the PLIF images.
