This tangential flow is referred to as wake rotation.

In protein purification, the term Tangential Flow Filtration ( TFF ) is used to describe cross-flow filtration with membranes.
3.
The stator concentrates the thrust in axial direction and reduces energy wasted in the tangential flow ( therefore eliminating torque on the hull ).
4.
Despite the generally higher volume fraction of rays in hardwoods ( typically 15 % of wood volume ), the rays are not particularly effective in radial flow, nor are the pits on the radial surfaces of fibres effective in tangential flow ( Langrish and Walker, 1993 ).
