An immersed boundary method on unstructured meshes is used in serial eddy-resolving simulations of turbulent flows over individual bodies with a changeable configuration and position. The corresponding numerical technique is based on mesh deformation and dynamic adaptation of a moving mesh without changing its topology. The described approach makes it possible to substantially reduce the computational costs of serial computations with variations in geometric parameters aimed at optimizing the shapes of airfoil elements. The performance of the technique is demonstrated by simulating the aeroacoustic properties of a two-element airfoil segment involving a leading-edge slat with changeable geometry.
