In physical modeling, especially in the field of wind tunnel tests, dimensional analysis is essential, but the existing dimensional analysis methods are difficult to select the appropriate physical quantities. Therefore, based on the improvement of existing dimensional analysis methods for wind tunnel tests, a set of optimized dimensional analysis methods for wind tunnel tests based on Buckingham Pi theorem was derived in this paper, and then we put forward an aerodynamic simulation experiment based on fluent to verify this method.

Research on optimize application of Buckingham Pi theorem to wind tunnel test and its aerodynamic simulation verification
