Abstract

Plasma actuators are all electrical devices capable of altering flow paths and reattaching separated boundary layers. The application to low pressure turbine stages in axial turbine engines indicates further fuel efficiency improvements at low Reynolds numbers. Using wind tunnel experiments, a numerical plasma model through steady-state simulations with RANS turbulence modeling was developed. Reasonable agreement has been observed in the calibration of the numerical plasma model to experimental data. Further parametric studies are considered, aiming to optimize control, reduce pressure loss for turbine stages, and reduce actuator power consumption.
