Disclosed is a vortex generating device (1) comprising a body (10), extending between a leading edge (11) and a trailing edge (12). The body, in profile cross sections (14, 15) taken across the spanwise direction (s), exhibis an airfoil-shaped geometry. Each airfoil-shaped profile cross section has a camber line (13) extending from the leading edge to the trailing edge, at least two of the camber lines exhibiting different camber angles, such that the body exhibits at least two different flow deflection angles along the spanwise extent. The body further comprises a first surface (16) extending between the leading edge and the trailing edge on a first side of the respective camber lines and a second surface (17) extending between the leading edge and the trailing edge on an opposite second side of the respective camber lines. The trailing edge extends from a first spanwise end (121) to a second spanwise end (122), and the trailing edge, when seen from a downstream viewpoint, comprises a first section (123) in which it is convexly shaped on the side of the first surface (16) and is concavely shaped on the side of the second surface (17), and comprises a second section (124) in which it is concavely shaped on the side of the first surface (16) and is convexly shaped on the side of the second surface (17). An imaginary trailing edge diagonal (131) extends straight from the first spanwise end (121) of the trailing edge to the second spanwise end (122) of the trailing edge. When seen from the downstream viewpoint, the trailing edge crosses (12) the imaginary trailing edge diagonal (131) exactly once at one diagonal crossing point (151).
