Abstract

Heat transfer
Film cooling, Pressure loss, Turbine blade
This paper discussed about Heat Transfer rate in gas turbine blade. Theseadvance days we need highly performance machinery. In modern gas turbine when we need high thermal performance then we need to improve high heat transfer rate. Entry pressure and temperature is very high in Gas turbine because of this improve the thermal efficiency and performance of gas engine. Major problem is enhancement of heat in gas turbine blade and this enhancement results in thermal and mechanical stress. This heat increase can be minimize by (i) applying thermal barrier coating on the surface, and (ii) providing coolant to the surface by injecting secondary air. Experiments were performed in blade tip. Film-cooling effectiveness or degree of cooling was assessed in terms of cooling hole geometry, blowing ratio, free stream turbulence, coolant-to-mainstream density ratio, purge flow rate, upstream vortex for blade platform cooling and blowing ratio, and upstream vortex for blade span cooling. The blade tip study was performed in a blow-down flow loop in a transonic flow environment. The degree of cooling was assessed in terms of blowing ratio and tip clearance. Limited heat transfer coefficient measurements were also carried out. Mainstream pressure loss was also measured for blade platform and blade tip film-cooling with the help of pitot-static probes. The pressure sensitive paint and temperature sensitive paint techniques were used for measuring film-cooling effectiveness whereas for heat transfer coefficient measurement, temperature sensitive paint technique was employed.
