Numerical investigation on swirl flow through burner with effect of rotation

The performance of the gas turbine system used in aviation depends on the nature of flame that occurs at the burner’s vent placed in the combustor. The recirculation zone enhances the rate of combustion and thereby its efficiency. The flow of air-fuel blend in a swirl through the burner increases recirculation. The research proposed in this work concentrates on the study of variation in the pressure and velocity of the flame propagating from the burner. In the current analysis, parameters influencing the flame velocity and pressure have been taken into consideration for further investigation. The investigation has been carried out in ANSYS. The results of the investigation show that the combustion is enhanced at a higher Reynolds number (Re) and elevated swirl angle. The examination of swirl flame was also carried out with the presence and non-presence of rotation of burner. These results indicate that there occurs a 5% increase in the recirculation due to the presence of rotation of the burner.
