AB - In this study, causes of increasing the mass flowrate for the shrouded horizontal axis wind turbine rotor were investigated numerically with comparing three shroud types, such as airfoil shroud and other two simple shrouds using constant thickness structure. Conical diffusers with and without the brim were used for other two simple shrouds. In particular conical diffuser with the brim was named wind-lens. The GOE 417 cambered airfoil with two angle of attacks, that is, 5° and 10° was used for airfoil shroud’s section. The flow field was assumed to be two-dimensional incompressible turbulent flow. The EDISON-CFD based on the LU-SGS for time marching and the Osher’s upwind scheme for spatial finite difference to solve the Reynolds-averaged Navier-Stokes equations was adopted to investigate the change of mass flowrates for various shrouds. Circulations around all of shrouds and pressure differences between inlet and outlet of the shrouds were calculated to investigate causes of increasing the mass flowrate. It turns out that the wind-lens is the best choice to maximize the mass flowrate for the given angles of attack of shroud’s section.
