Design and analysis of subsonic open wind tunnel by using Computational Fluid Dynamics at different inlet velocities is carried out in this paper. The governing equations of fluid flow were solved numerically to calibrate the wind tunnel using computational fluid dynamics method by considering the flow as steady, incompressible, turbulent and three dimensional. To obtain a robust numerical simulation, coupled algorithm is used for pressure-velocity coupling with second order and second order spatial discretization to solve all the governing equations involved.
