This paper's purpose is to deal with single point and multipoint optimization of an airfoil. The aim of the paper is to discuss optimization in several design points (multipoint optimization) and compare the results with those of optimization at a specified design point.

    Design/methodology/approach

    A gradient-based method is adopted for optimization and the flow is governed by two dimensional, compressible Euler equations. A finite volume code based on unstructured grid is developed to solve the equations.

    Findings

    Two test cases are studied for an airfoil with initial profile of NACA0012, with two types of design variables. And at the end a multi-point case is presented.

    Originality/value

    The advantage of this technique over the other gradient-based methods is its high-convergence rate.
