Effects of Swirl Flow on Spray Characteristics in a Swirl-Stabilized Combustor

Abstract

This paper presents experimental data on the characteristics of a kerosene spray flame produced by a hollow-cone pressure-atomized nozzle in a swirl-stabilized combustor. These acquired data include the volume flux distribution, size and velocity distribution, measured by use of Phase Doppler Particle Analyzer (PDPA). The effects of swirl number on different parameters, recirculation zone, and stability of the flame is investigated. The data is offered for use in assessments of two-phase flow computational methods as are useful to gas turbine and furnace combustors design procedure. The overall characteristics of this spray flame were defined.
