N2  - In this study, the flow structure close to the surface of the non slender diamond wing was investigated both qualitatively and quantitatively using dye visualization and the 3-D Particle Image Velocimetry (PIV) technique. The flow structure and formation of the vortex breakdown were studied by varying the yaw angle of the wing within the range of 0o≤θ≤15o for the angle of attack of α=7° and Reynolds number of 10 000. After a certain distance from the wing apex, a stagnation points and onset of vortex breakdowns took places on the central axes of spiral vortices that occurred over the wing surface for the angle of attack of α=7°. When the yaw angle was increased the locations of vortex breakdowns approached to the wing apex, but, the other one moves towards the trailing edge
