Structure of High-Speed Sprays.
Abstract
The conclusions are that: the breakup of full-cone Diesel jets is due primarily to aerodynamic interaction between the liquid surface and the chamber gas; the initial average size and velocity of the drops formed by the breakup of the outer surface of the jet can now be estimated and so can the length of the intact core but with greater uncertainty; after breakup a steady full-cone spray undergoes a development similar to that of incompressible jets; in Diesel engines it is the development region that is of importance; the major parameter in the difference between full-cone sprays and incompressible jets is the liquid-to-gas density ratio; in the absence of vaporization the most advanced of the available spray model reproduce full-cone sprays with adequate realism for applications; it is not yet known how vaporization changes the structure of these sprays and if available models adequately reproduce the changes.
