Аннотация:An immersed boundary method on unstructured meshes is used in serial eddy-resolvingsimulations 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 amoving mesh without changing its topology. The described approach makes it possible to substantiallyreduce the computational costs of serial computations with variations in geometric parameters aimedat optimizing the shapes of airfoil elements. The performance of the technique is demonstrated by sim-ulating the aeroacoustic properties of a two-element airfoil segment involving a leading-edge slat withchangeable geometry
