sheared flow (medicine) and comet (iou)


sheared flow (medicine)


sheared flow
<radiobiology> Fluid flow where the magnitude of the fluid velocity changes along a direction perpedicular to the direction of the fluid flow. (Freeway traffic often exhibits sheared flow in that traffic in the fast lane moves more rapidly than traffic in the slow lane with the exits.) Sheared flow typically correlates with reduced transport and enhanced confinement. (This definition is rather informal and may not be fully technically correct - R.F. Heeter)
