Computed Effect of Varying Tip Clearance and Axial Gap on Gas Turbine Stage Performance Part (I): (Steady Flow)

turbine, imprecise axial gap and tip clearance are two significant sources ofinefficiency. This work investigates the effect of change in parameters such asaxial gap and tip clearance on axial flow gas turbine used in power generation.Different combinations of axial gap and tip clearance have been tested to analyzethe performance of the turbine. It is revealed that the axial gap of 18.5% of axialchord and 2.4% tip clearance of blade height is the optimum set value for themaximum performance
