MODELING AND CFD ANALYSIS OF SWIRL CAN TYPE COMBUSTION CHAMBER

Abstract

New computational methods are continuously developed in order to solve problems in different engineering
fields. One of these fields is gas turbines, where the challenge is to make gas turbines more efficient and to reduce
emissions which affect the environmental balance. One of the main parts of a gas turbine that can be improved is the
combustion chamber. In order to optimize the combustion chamber, both experimental and numerical methods are called
for. Another topic of interest is to change the mixture in combustor and analyse its effects for reducin g emissions. This
paper describes a model of Swirl Can Type Combustion Chamber that is numerically reliable, mesh independent and fast.
This paper presents a computational study of the flow field generated in Can combustion chamber and how that flow field
convicts through the swirler. Specifically, the efect that the flow field acting at the outlet is studied. This paper presents
the results of computational simulations done in parallel with e experimental. In comparisons of computational predictions
with e xp e ri me nt al data, a reasonable agreement of the mean flow and generated swirling effect i n the combustor after
changing the swirl angle, pressure loss at outlet may be changed.
