Design and Numerical Analysis of an Open-Circuit Low-Speed Wind Tunnel

Abstract

The design and numerical analysis of a 3D open-circuit, low-speed, with a maximum velocity of 20 m/s in the test section, wind tunnel is presented. Two diffusers’ angels are numerically tested in order to reduce the pumping power of the fan. The proposed design is analyzed using three-dimensional, turbulent, incompressible flow using ANSYS FLUENT. Numerical results show that the velocity as well as the pressure are uniform in the test section and no vortices are formed in the diffuser section which affirms the success of the proposed design.
