Growing drop technique has been developed for measuring the dynamic behavior of drop at the exit of a fine capillary where a drop grows. In this study, the system was designed to simulate the electrospinning process without applying a high voltage to understand the dynamic behavior of PVA solution before ejecting a fluid jet. The system associated with Image analysis technique and numerical analysis method has been developed. Important parameters of the drop formation were extracted by programming image analysis techniques such as fill boundary method and chain cord algorithm. To obtain statistically meaningful data, numerical analysis techniques were programmed. The diameter, volume, contact angle and velocity of fluid head of PVA solution at the exit of a fine capillary have been measured and calculated with various hydrostatic pressures. The integrated system of image analysis and numerical analysis methods has been successfully used to investigate the effect of the hydrostatic force on drop formation.
