Interferometric Studies of Vapourising and Combusting Sprays 830244
Holographic interferometry has been applied to the study of concentration and temperature distribution in transient vapourising non-burning and burning fuel sprays in a quiescent bomb.
Empirical relations have been obtained to describe the axial and radial variations of concentration in the vapourising non-burning spray, and to evaluate penetration and air entrainment of the free and wall jet regions of non-burning and burning sprays. The movement of the ‘tail’ of the spray in the post injection period has been studied.
Finally, data are presented for species concentration and temperature profiles within the burning spray.
