Abstrakt

Air cooling is widely used technique to shield the turbine aerofoils against hot flue gases. The cooling of a gas turbine blade using wet air and dry air as a coolant is analytically investigated. The investigation is carried out considering effect of rotation for inward and outward flow of coolant. Wet air cooling performance is compared with dry air cooling. It has been observed that wet air provides better cooling and the performance improves with increase in relative humidity. The temperature of blade at tip decreases from 1293.44 K to 1172.6 K when relative humidity of wet air is increased from 10% to 90%. Cite this Article Snehal N. Patel, Dilip S. Patel, Kedar A.
