Abstract

Schlieren high speed videography was employed to ascertain the geometric properties, compressible flow behaviour and the flow field of Compressed Natural Gas (CNG) jets. Axial and radial penetration, velocity, and dispersion have been studied comparatively. Schlieren high speed imaging reveals the dynamic flow behaviour of the delivery event, namely barrel Mach disc formation and mixing at the shear layer alongside other geometrical features; spreading rate, self-similarity, velocity and penetration. New findings of high-pressure gaseous fuel delivery are presented based on observations in a constant-volume chamber that replicates engine conditions. A novel analysis method for characterising structural dynamic properties of the gas jet are also presented alongside a new delivery method.
