Investigations of Gas Turbine Characteristics by Varying Tip Clearance and Axial Gap
نویسندگان
چکیده
It is desirable to further increase the efficiency of turbo machines. In axial flow gas turbine, imprecise axial gap and tip clearance are two significant sources of inefficiency. This work investigates the effect of change in parameters such as axial 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 analyze the performance of the turbine. It is revealed that the axial gap of 3.5 mm and 5% tip clearance is the optimum set value for the maximum performance.

متن کاملAssessment of various rotor tip geometries on a single stage gas turbine performance
Tip leakage loss introduces major part of losses of the rotor in axial gas turbines. Therefore, the rotor blade tip has a considerable effect on rotor efficiency. To understand the flow physics of the rotor tip leakage, we solve the flow field for different tip platforms (passive flow control) and by considering coolant tip injection (active flow control). Various blade tip configurations s...
