This paper experimentally investigates a highly-loaded 1.5-stage transonic axial compressor, which comprises variable inlet guide vane, BLISK rotor, and stator in tandem arrangement. A detailed comparison between the newly designed compressor stage reference with conventional design was conducted by using extensive instrumentation. Thus, steady unsteady phenomena—focusing on aerodynamic aeroela...

Biomass based Indirectly Heated combined heat and power plant can be an excellent option for community scale power generation. The thermal performance of such a plant employing air-turbo generator block and bottoming steam turbine block has been analyzed over a range of pressure ratio (2-16) and for different turbine inlet air temperatures (1073, 1273 and 1373K). The conventional GT combustion ...

In this paper, aerodynamic blade design optimization for a transonic axial compressor has demonstrated by using an evolutionary-algorithm-based high-fidelity design optimization tool. The present method uses a three-dimensional Navier-Stokes solver named TRAF3D for aerodynamic analysis to represent flow fields accurately and the realcoded ARGA for efficient and robust design optimization. The p...
