1 The fluid spray exits the nozzle in the form of a stream, which decays rapidly to ligaments that break up into droplets. All these transitions occur in a very short time and region. This work provides a fundamental analysis of the jet stability in general form, but it is devoted particularly to fluidic jets. Such jets exist in different industrial applications; automobile windshield washer and diesel fuel injector sprays are good examples. A computational analysis is developed that predicts the break up distance and velocity of the fluidic jets, which is one of the important factors that helps in prediction of the spray pattern and droplet strike location. Thus reduces number of the required prototypes and saves time and cost. Also, a parametric study is conducted to analyze the effect the jet breakup on the spray trajectory.
