[en] Spray characterization, i. e. a velocity map of the liquid and gaseous phases and the sizing of the liquid droplet, remains of a great importance in different industrial applications such as in the automotive or pharmaceutical industries. Correlations capable to faster this characterization already exist. They allow the evaluation of the droplet Sauter Mean Diameter in a precise location of the spray using non-dimensional numbers involving physical and chemical properties of the liquid and the spray operative conditions. This paper concerns the possibility to include in the correlative laws also the effect of the liquid viscosity through the introduction of the Ohnesorge number (Oh). In order to achieve this goal an extensively experimentalcampaign is performed, by means of a Phase Doppler Interferometer, for size and velocity measurements in a full cone spray.
Parameters as the hydraulic diameter of the nozzle, the operatingpressure and the liquid viscosity are varied in order to cover large range of Weber and Ohnesorge numbers.
