Ky. Chung et al., DEAN VORTICES IN CURVED TUBE FLOW .5. 3-D MRI AND NUMERICAL-ANALYSIS OF THE VELOCITY-FIELD, AIChE journal, 39(10), 1993, pp. 1592-1602
The velocity contour profiles within Dean vortices produced by flowing
water in a solid-walled curved tube are quantitatively measured. Magn
etic resonance flow imaging using flow encoding with spin warp imaging
is used in two and three dimensions to obtain these velocities. These
experimental measurements are then compared with simulations obtained
from solutions of the Navier-Stokes and continuity equations for thre
e axial flow rates. Numerical solutions were obtained with a finite vo
lume method for curved tube Poiseuille flow.
