Original Abstract

This contribution presents an experimental investigation of spray characteristics of a spill-return pressure-swirl atomizer for a small-sized turbojet engine by means of Particle Image Velocimetry. The nozzle was tested on a cold test bench at atmospheric pressure and room temperature. Measurements were carried out in an axial section of the spray cone with various single-camera and stereoscopic PIV configurations. Results of our measurements provide a quantitative visualisation of the spray flow fields in regimes based on the engine operating conditions. Comparison of velocity profiles obtained from the individual configurations is presented and discussed.
