my.uniten.dspace-353522024-12-15T02:00:29Z CFD simulation on the temperature spread problem in a silo type gas turbine combustor Rishi Kumar Sundarass Gas turbine TJ778.R57 2015 A Computational Fluid Dynamic (CFD) simulation of a silo type gas turbine combustor was carried out. This type of gas turbine usually has two identical silo type combustors on its left side and right side. Each combustor has eight burners, which can be fuelled with distillate gas or combination of both. Angle 45° is taken as the baseline angle to act as the reference angle for this research. Study is conducted to see the effect of varying this swirl angle on the combustion profile and temperature spread inside the combustor. The model of the combustor is created using CFD software GAMBIT. The simulations were carried out at swirl angle of 35°, 45° and 55°. The results of the simulation are analysed to see the temperature pattern and velocity pattern at the combustor outlet. Parameters such as Maximum Temperature (Tmax), Minimum Temperature (Tmin), Average Temperature (Tavg), Differential Temperature (AT) and Maximum Velocity () across the combustor outlet are tabulated and analysed. The parameters stated above are important to determine hot spot and uneven temperature spread at the combustor outlet at the various swirl angle. The results will be compared with the baseline data at 45° as it will act as the reference. The velocity (U) near the swirl increases as the swirl angle is increased. This shows that there is better mixture of fuel and air at high swirl angle. The result indicates that the swirl angle plays an important part in uneven temperature spread problem. From the analysis of the results it can be concluded that the best possible angle is 55° and above, thus to improve the temperature spread problem the swirl value should be increased. 2024-12-13T08:23:42Z 2024-12-13T08:23:42Z 2015 Resource Types::text::Final Year Project https://irepository.uniten.edu.my/handle/123456789/35352 en application/pdf |
