Numerical optimization in a structured/unstructured grid

  • Much attention had been shifted to the unstructured grid methods. It was due to the relative ease with which these methods could be applied to solve flow problems around complex geometries and the ease with which local refinement of an unstructured grid could be carried out. Numerical optimization and inverse design computation with the viscous flow field were carried out on a structured/unstructured grid. Both mono-objective/bi-objective aerodynamic optimization were included in the numerical optimization. The conventional inverse design, in which the airfoil shape was modified by the required target pressure distribution imposed on an initial airfoil, was realized by present optimization method. Numerical results illustrate that the present method is an efficient tool for airfoil design.
