Abstract
Predicting the droplet sizes produced by a jet is important in fields ranging from the pharmaceutical industry to emergency planning in the event of a deep-sea well blowout. Current scaling models are usually based on experimental results obtained using a straight pipe entering a quiescent media. As the process of breakup is governed by the local turbulent fields, the history of the jet fluid upstream from the entry to the quiescent domain is important. Turbulence generated by the extreme shear gradients arising at obstruction within the pipe will be advected a significant distance downstream, including beyond the jet exit. This work shows that an orifice plate inserted into a pipe upstream of the exit alters the jet that emerges, even when the orifice plate is a several diameters upstream of the opening. The effect in general is to enhance the spreading of the jet sue to the influence of the turbulence kinetic energy generated at the orifice plate that has been transported into the exiting jet.
