A simple method of determining normalizing spray flux distribution was demonstrated applying flow visualization and the measurement of droplet distribution using a patternator. Two reservoirs are used to contain the working fluid (water) under pressure. This liquid is injected into still air from two nozzles. The nozzles are adjustable to eliminate any misalignment of the water jets. The surface tension coefficient was measured using an automatic surface tensiometer employing the plate method. The atomization process was visualized using a high-speed video camera in conjunction with a backlighting technique. The 3D-printed patternator was demonstrated to be useful for the 2D measurement of spray mass flux distributions. The spray mass flux distribution was normalized as a function of normalized distance after atomization was complete. The flux distribution at any location could be calculated from the normalized distribution convergence considering the spread of the spray.
