Aerodynamic optimization design of airfoil based on correlation analysis

A new optimization model is established from the partial correction coefficient between geometric parameters and flow variables by using computational fluid dynamics (CFD) and correlation analysis. The new model is used to optimize airfoil HSNLF-0213. First, the correction between geometric parameters and flow variables is analyzed by the partial correction analysis method, and the design rules are established. Second, these design rules are applied to develop the optimization model with a single object to satisfy the demand of multi-objective optimization. Finally, the new optimization design is performed, and the optimum results are achieved. Applying this model contributes to design efficiency and good results are obtained. It is possible to introduce this method based on the partial correction analysis into optimal design.
