Abstract

To meet the future demand for a wide-range flow of low-pressure turbines in wide-space and wide-speed domains of aero-engines， it is difficult to achieve a wide-range flow while maintaining high efficiency. To achieve efficient operation of the turbine with a wide mass flow range， numerical simulations for low-pressure turbines using a coupled regulation method were carried out. The effects of two flow regulation methods， namely， individual partial admission and coupling of adjustable guide vanes and partial admission， on the aerodynamic performance and flow loss of the turbine were analyzed. The numerical results show that the coupled regulation method can significantly improve the aerodynamic efficiency of the turbine at a higher expansion ratio. When the expansion ratio is 1.555， the coupled regulation method can increase the efficiency by up to 2.6% compared with the individual method of adjustable guide vane and achieve an average of 0.6% improvement in efficiency compared with the individual method of partial admission. When the expansion ratio is 1.8， the coupled regulation method can increase the efficiency by up to 5.8% compared with the individual method of adjustable guide vane and achieve an average of 1.9% improvement in efficiency compared with the individual method of partial admission.

Key words： flow regulation; adjustable guide vanes; partial admission; coupled regulation; aerodynamic efficiency
