  • Wake interaction of a rectangular prism behind a geometrically accurate porous barrier
    Telenta, Marijo ...
    Vortex wake interaction of a rectangular prism is numerically investigated. The wind barrier is accurately geometrically represented with a three-dimensional model in the numerical simulation. The ... barrier model consists of horizontal bars with different inclination angles. The unsteady Reynolds-averaged Navier-Stokes (URANS) computation is applied because the flow is not statistically stationary. The shear stress transport (SST) k- turbulence model is used because it shows good behavior in adverse and separated flows. Experimental study is performed to confirm the numerical data. The aim is to enhance the present level of understanding regarding bluff body wake interference flow and analyze the barriers bar inclination effect on the sheltered object. As the bar inclination angle decreases, the bleed flow gets stronger, which results in a smaller reduction of the drag imposed on the sheltered object. The turbulent structures between the barrier and the sheltered object decrease as the bar inclination angle decreases.
