Research area: Gas turbine combustor liner cooling tecchnology.
Co-Guide: Prof. C. Balaji
To increase the efficiency of a gas turbine, temperature and pressure in the combustor should be increased. The metal surface of the combustor cannot withstand at elevated temperatures. The surface of the combustor has to be cooled to withstand at high temperatures. One of the cooling techniques is film-cooling in which cooling air (secondary air) passed as a film in between the hot gases and the surface. So, the cooling film will protect the metal surface from hot gases by keeping at low temperatures. On the other hand, the future Aero engines will work on lean mixtures. The amount of air in the combustor will increase significantly because of the film cooling air which affects the combustion and reduces the efficiency of the gas turbine engine. Since the air available for cooling is limited and overcooling is also not suggested. so, an optimized flow condition and cooling hole geometrical configuration is required.
In the present study, the effect operating parameters such as blowing ratio (BR), density ratio (DR), Reynolds number of coolant and geometrical parameters on the film cooling effectiveness and Nusselt number is analysed.
