Effect of velocity variation at high swirl on axial flow development inside a can combustor

The main purpose of this paper is to study the internal flow effect of varying the inlet velocities inside a combustor. The flow field inside the combustor is controlled by the liner shape and size, wall side holes shape, size and arrangement (primary, secondary and dilution holes), and primary air...

Electronics Nuclear engineering The main purpose of this paper is to study the internal flow effect of varying the inlet velocities inside a combustor. The flow field inside the combustor is controlled by the liner shape and size, wall side holes shape, size and arrangement (primary, secondary and dilution holes), and primary air swirler configuration. Air swirler adds sufficient swirling to the inlet flow to generate central recirculation region (CRZ) which is necessary for flame stability and fuel air mixing enhancement. Therefore, designing an appropriate air swirler is a challenge to produce stable, efficient and low emission combustion with low pressure losses.

Results show that the swirling action is augmented with the increase in the injection velocity, which leads to increase in core reverse flow, thus enhancing mixing of fuel and air in the combustion chamber Penerbit UTM 2014 Article PeerReviewed application/pdf en http://eprints.utm.my/id/eprint/52583/1/MohammadNazriMohd.2014_Effectofvelocityvariation.pdf Ishak, Mohamad Shaiful Ashrul and Mohd.
