Expert
In wind tunnel test, why are similarity of Reynolds Number between real bridge and model is often neglected? Wind tunnel test is often done to make sure aerodynamic stability of long-span bridges. To correctly conduct wind tunnel test, conditions of aerodynamic similarity should be made equal between the proposed bridge and the model. One of these conditions is Reynolds Number and is defined as ratio of inertial force to viscous force of wind fluid.
