A spray generated by two types of pressure swirl atomizers (PSAs) (i.e. spill-return and simplex atomizers) was examined by means of a volumetric 3-component velocimetry (V3V) measurement system (V3V-Flex©, TSI Inc.). The experimental setup is first described in this paper, and the image processing steps are outlined later. The 3D3C measurements of instantaneous droplet velocities were provided for several operating regimes, and the suitability of the V3V-Flex© method for the description of the 3D complex spray flow is depicted.
