Abstract
The aim of this study is to investigate the flow field characteristics of the radial-swirl burner which is developed for a small gas turbine. To create a stable flame during the combustion process, the burner has to create a reversal flow area or a recirculation flow. Without this zone, the combustion process cannot be created. Therefore, the characteristics of the flow field in the burner is very critical. The current study applied two types of the radial-swirl burner. One has a straight-type vane and the other has a nozzle-type vane. The flow angle of both types are varied from 40°, 50° and 60°. The mass flow rate of air is varied from 1.0 to 1.8 kg/min. The commercial computational fluid dynamic program, ANSYS FLUENT is also used. The results of the simulation are discussed in this paper.
