Vortex generating device

A vortex generating device, comprising:

• a body having a leading edge and a trailing edge, a streamwise direction (I) being defined from the leading edge to the trailing edge, the body further having a spanwise direction (s), and the body, in profile cross sections taken across the spanwise direction, exhibiting an airfoil-shaped geometry;
• each airfoil-shaped profile cross section with a camber line 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 direction;
• a first surface extending between the leading edge and the trailing edge and including airfoil-shaped profile lines on a first side of the respective camber lines and a second surface extending between the leading edge and the trailing edge and including airfoil-shaped profile lines on an opposite second side of the respective camber lines, and the first and second surfaces joining each other at the leading edge and at the trailing edge;
• the body in a trailing edge region exhibiting a corrugated shape wherein the first surface exhibits a flute extending upstream from the trailing edge and the second surface exhibits a ridge extending upstream from the trailing edge opposite said flute;
• the trailing edge, when seen from a viewpoint downstream the body, exhibiting an undulating shape, wherein the trailing edge when seen from said downstream viewpoint includes a plurality of adjacent trailing edge sections which abut each other at respective corners and include respective angles (a, b, c, d) with each other,
• at least first trailing edge sections of the plurality of adjacent trailing edge sections being arranged across a trailing edge median line;
• at least one fuel supply plenum being provided inside the body and at least one fuel discharge opening being provided at a respective one of the first trailing edge sections, whereby the fuel discharge opening is in fluid communication with the fuel supply plenum, wherein
• adjacent corners of the trailing edge are arranged across a trailing edge mean line and configured to generate co-rotating vortices, the co-rotating vortices generating a shear layer between them at a location where the fuel discharge opening is located.
