Paper Abstract

The collecting efficiency of surgical smoke evacuators depends strongly on the design of the suction nozzle. In order to study the flow conditions at the nozzle entrance we developed methods to visualize the flow in the surrounding area. The experimental set-up for visualization and recording of the streamlines is described. Flow patterns recorded on a video recorder allow us to estimate the efficiency of a particular nozzle design under various experimental conditions. The turn-over from laminar flow to turbulent flow due to the laser generated fume can be studied in detail.
