Simulated axial fluid velocity profiles versus distance from the inner capillary nozzle aperture. The error bars are the standard deviation of the distribution of flow velocities present within 5 μm from the axis of flow at each position (i.e., a measure of the transverse inhomogeneity in the system). The simulation parameters (〈Vout〉 and 〈Vin〉 used to obtain each curve are given in the figure legend.
