Abstract
Investigations were given on effects of atomizing air velocities (differential pressure), fuel flow rates, and air flow swirling on size distribution of grains in the vapor, when fuel nozzles of airblast micronizing type used in combustors in aircraft gas turbines are used in single elements and combined with swirlers. The fuel nozzles used in the experiment were a fuel nozzle of prefilming system. The experiment used water as a fuel (liquid). The experimental equipment comprised a spray testing equipment body, and air and liquid supply-discharge systems. For measuring the grain size distribution, a non-contact grain size distribution measuring equipment utilizing laser scatter intensity patterns was used. The atomizing air velocities gave extremely large effects on grain micronization, but little effect on the fuel flow rates. The dependence of the sauter mean diameter (SMD) on the atomizing air velocities was in inverse proportion to about 1.5 power of the atomizing air velocity when a single fuel nozzle was used. When the nozzle is combined with a swirler, its dependence on the atomizing air velocities has grown stronger. The grain size measured apart from the swirler-combined nozzle was smaller that in the use of a single nozzle. 7 refs., 12 figs.
