In the current world almost all the aerodynamic bodies are designed and then analysed for preliminary results. These designs however need to be verified and tested in real time. To study various flow parameters and response of any aerodynamic body under varying conditions and orientations, wind tunnels are used. These tunnels are usually of open or closed types which can be used to conduct studies over flows past any aerodynamic body or structure. The work focuses on aerodynamics design of a Wind Tunnel to simulate and disseminate results of subsonic flows, measurement of lift coefficient (CL) and drag coefficients (CD) which can be used to determine performance of any aerodynamic body. The proposed tunnel was designed based on flow theories to obtain a preliminary design of subsonic tunnel. An open type wind tunnel is designed using CAD tool which is further simulated using ANSYS CFX. The CFD results are examined to decide an optimized design which is then fabricated to carryout experimentation. The model comprises of three parts namely contraction cone which is a convergent tract, test section and a diffuser commonly referred to as diverging tract. The wind speed of the tunnel is varied with the use of a variable transformer. The tunnel manufactured is used to study lift and drag forces acting on different aerodynamic structures and designs. The aerodynamic study of CLARK Y air foilis carried out for testing in wind tunnel after a standard calibration.
