A numerical and experimental study of a thin, high cambered airfoil at a low Reynolds number

摘要

In the framework of the development of new aerodynamic design concepts, a joint numerical/experimental analysis has been performed on a 2D thin, high cambered airfoil at a low Reynolds number. The experimental investigation has been performed by means of the Pressure Sensitive Paint Technique (PSP) and Particle Image Velocimetry (PIV). These techniques have been selected for their characteristics of low-intrusivity and high spatial resolution. Details about the experimental set-up and results shall be reported. The experimental investigation has been intended to obtain detailed information about the pressure field and to detect flow characteristics on a non-conventional airfoil. Experimental data have been compared with numerical results obtained by FLUENT commercial code. Results will be presented in terms of experimental and numerical velocity fields around the model and in terms of lift characteristics.
