A new measuring method is proposed, which measures the atomization characteristics of a non-evaporating, axi-symmetric diesel spray by means of an image analysis of high speed shadow photographs. The instantaneous sauter mean diameter and the fuel concentration in the spray are calculated of the splay axis and in the radial direction and the data of the fuel injection rate, using an onion peeling model. Some examples of application of this method to eight different diesel sprays are demonstrated, and the results are compared to predicted results by the conventional immersion method and a quasi-steady one dimensional spray model.
