03.1 - Aerodynamics – CFD Methods and ValidationEFFECTS OF GEOMETRY PARAMETERS ON AERODYNAMIC CHARACTERISTICS OF ROTOR AIRFOIL IN REVERSE FLOWC.-P. Liu¹, W.-P. Song¹, S.-Q. Han, Sichuan University, China; Z.-H. Han¹; ¹Northwestern Polytechnical University, China An improved high order WENO scheme and IDDES method are used to study the aerodynamic characteristic of rotor airfoil in reverse flow. OA312 airfoil is chosen and morphed with different design parameters. Aerodynamic coefficients of these airfoils are simulated and compared to analyze the influence of different design parameters, which can be used to guide the design of new rotor airfoil. |
