Abstract: In this paper we investigate acceleration of flow-focused micro-jets under an applied electric field. Such thin and fast jets are needed, for example, for the delivery of protein crystals in X-ray free electron laser experiments. This contribution focuses on analysing the jet acceleration of liquid consisting of 50 % vol water and ethanol mixture, which was focused with nitrogen gas and subjected to 0 - 7 kV electric potential between a submerged electrode and electrode downstream of the nozzle. The analysis is based on the recently published measurements [1] and consists of automatic recognition and capture of jet geometric properties via computer vision. We discovered that micro-jets under strong electric fields are exposed to acceleration up to four orders of magnitude larger than the conventional micro-jets.
