Abstract

A generic feature of a wide variety of central venous catheters, which are typically located within the superior vena cava (SVC), is a jet from a side hole of the catheter tip. Particle image velocimetry is employed in conjunction with a scaled-up water facility, in order to characterize the structure of the jet as a function of dimensionless hole diameter and jet velocity ratio. Quantitative patterns in the radial and crossflow planes of the catheter-SVC system define the jet evolution. It has distinctive features, relative to the classical jet in a crossflow, which issues from a small opening in a planar surface into a region of large extent.
