Abstract

The present paper discusses experimental work to investigate the influence of swirl generator characteristics on the aerodynamic properties of unconfined turbulent swirl jets and the combustion behavior of unconfined swirl flames.

The distribution of the tangential velocity component at the burner exit characterizes different types of vortices typical of each swirl generator. These different vortices may be described by a modified solid body vortex approach. Swirl generators producing similar vortices generate swirl jets and swirl flames with similar properties.

Swirl intensity is described by means of a swirl number. The paper discusses the prediction of swirl numbers from swirl generator design data and the validation of these numbers by measurement.
