REAL FLOW OVER A BODY OF REVOLUTION AT ANGLE OF ATTACK

Abstract

Certain conclusions can now be made regarding the problem. The vorticity is generated by a skewness of the boundary layer resulting from the low velocity regions near the body being influenced by the pressure forces and viscous forces. ORTICITY INCREASES IN STRENGTH ALONG THE BODY LENGTH. It is transported with, and diffuses through, the flow thus covering a larger region on the top part of the body than on the bottom. As the vorticity is transported with the flow it starts to assume more of an axial direction. The strongest component of vorticity is that in the circumferential direction and is associated with the axial component of the boundary layer flow. The axial component of vorticity is also an important component. A symmetrical concentrated vortex pair, fed by a weak vortex sheet, does not exist. The axial component of the vorticity gives the impression of the existence of this vortex pair.
