Axial Turbine Performance Enhancement by Specific Fluid Injection

Extensively used in modern gas turbine engines various applications, ranging from aerospace, marine and terrestrial propulsion to power generation pumping, the axial flow turbines have been continuously updated are now capable of high performances reliability. One drawback that has not yet resolved is poor performance at lower- than-nominal regimes. To solve these shortcomings, a new method improve partial regimes by specific fluid injection proposed this paper. The influence system determined conducting numerical analyze, studying different parameters (i.e., number, dimensions position orifices) on overall turbine. study completed single stage 1300 KW with being applied settings across working line. results show generated can be enhanced as much 30% for configurations number small size
