MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202521059835 A) filed by Parul University (Parul Institute Of Engineering And Technology); Singh Anup Tejnarayan; Balaji K; Singh Nishikant; and Yash Chauhan, Vadodara, Gujarat, on June 23, 2025, for 'a system and method for suction area control to delay stall in horizontal-axis wind turbine airfoils.'
Inventor(s) include Singh Anup Tejnarayan; Balaji K; Singh Nishikant; and Yash Chauhan.
The application for the patent was published on Dec. 12, under issue no. 50/2025.
According to the abstract released by the Intellectual Property India: "A boundary layer aerodynamic control system is disclosed for horizontal-axis wind turbine airfoils (10) having an upper surface (14) comprising a defined suction region (18) and an adjacent injection region. The inventive system integrates a suction area mechanism (12) with continuously arranged suction ports (16) in an upper surface recess (26) to remove low-energy fluid, and an injection area mechanism (20) featuring a fixed array of injection ports (22) interconnected via an internal flow channel network (24) for delivering a pressurized co-flow. The system maintains a suction-to-injection area ratio of 1:1, targeting zones prone to flow separation, and incorporates a boundary layer control interface (28) to optimize aerodynamic performance through computational simulations and experimental validation."
