Circumferential induced velocity
WebIn mechanics, a cylinder stress is a stress distribution with rotational symmetry; that is, which remains unchanged if the stressed object is rotated about some fixed axis. Cylinder stress patterns include: circumferential stress, or hoop stress, a normal stress in the tangential ( azimuth) direction. axial stress, a normal stress parallel to ... WebThe rear blade-element axial velocity components include the free stream velocity, V, the axial self-induced velocity, Wa,2, and the axial cross-induced velocity which the forward disk induces on the rear, Wa,1on2. The circumferential velocity components include the tangential velocity, Ω2∙r, the self-induced circumferential
