In the world of power generation and aerospace engineering, the limitations of traditional fluidic oscillators have hampered efforts to enhance turbine blade efficiency and airfoil performance. Current designs struggle to position oscillating jets effectively near the leading edge, where cooling and boundary layer flow control are critical. There is a pressing need for a fluidic actuator that can navigate highly curved geometries, providing targeted and efficient fluid flow in compact areas.
Our groundbreaking technology, developed by the pioneering researchers at The Ohio State University’s Aerospace Research Center Turbine Aerothermodynamics Lab, introduces a bistable fluidic actuator. This innovative device delivers an oscillating jet 90° out-of-plane from the inlet, utilizing a specialized cavity design that harnesses the Coanda effect. By creating a feedback loop, this actuator produces an oscillating fluid flow, enabling precise boundary layer flow control and effective film cooling on curved surfaces, such as turbine blades and airfoils.
