- W2362478850 abstract "A new method for the inverse problem of the airfoil is presented in this paper. With this method based on the dynamic evolution of airfoil, the unsteady flow governing equations are solved; the solution to the inverse problem is come true with great efficiency and speed.In the inverse problem, the coming flow conditions and the distribution of the tangent velocity of the target airfoil are given; the airfoil geometry shape needs to be determined. The key of the new method is to present a moderate process of airfoil evolution. In the concrete, the evolutionary velocity of the airfoil is expressed by the transportation relationship of the velocity gradient on the surface step-by-step, and then the whole evolution of the airfoil is implemented. Here, the Level-Set approach, which captures the airfoil figures in time, is adopted instead of moving curvilinear coordinate.In this paper, two verifiable examples are carried out, which are the incompressible irrotational flows around the Joukowski airfoil and around the arc airfoil, respectively. As results, the new method for the inverse problem of the airfoil leads to the considerable decrease of the calculation and the great efficiency and speed, and reveals the high-performance and rationality." @default.
