Abstract Experiments were conducted to assess the ability of a particle-counter-sizer velocimeter (PCSV) to measure droplet speeds in the developing region of an electrohydrodynamic spray. The working fluid, ethanol, was pumped through a stainless steel capillary tube at a constant mass flow rate. The capillary tube was held at various positive potential voltages with respect to an externally grounded funnel located below the tube. Data were acquired at two axial stations, directly under the capillary tip, in the developing region of the subject spray. The results indicated that the PCSV, with an experimental modification to the speed reduction process, performed well in this region. Speeds were measured at the near station within an average uncertainty of 2.2% and a corresponding maximum uncertainty of 3.0%; speeds at the far station were measured within an average uncertainty of 4.6% and a corresponding maximum uncertainty of 6.0%.
