Spray-wall interaction: an experimental study of multiple injections of standard diesel

Övrigt konferensbidrag, 2005

Spray-wall phenomena were investigated in a high-pressure/high-temperature spray rig with optical access. The spray impinged on a tempered wall 32 mm downstream of the nozzle tip. The properties that were studied were axial and radial penetration, and heat transferred between the fuel and the wall, and how these were influenced by fuel pressure, air density and wall temperature. The injection was split into two and the behaviour of the two injections was compared.
