Capillary cone jets are natural microfluidic structures arising in steady capillary tip streaming, whose paradigms are electrospray and flow focusing phenomena. In this work, we make a profound revision of the basic underlying physics of generic cone jets from thousands of experimental measurements, most of them reported in the literature. First, the boundaries of the stability region of steady jetting are calculated. We describe these limitations by instability mechanisms associated with the… CONTINUE READING
