Effect of Channel Bends on Transverse Mixing
Abstract
Velocity and tracer concentration measurements made in a meandering channel are used to discuss the effect of bends on the transverse mixing of a conservative tracer introduced into the flow. It is shown that bend induced spiral motion greatly enhance the mixing potential of meandering channel flows; The magnitude of the normalised transverse mixing coefficient is observed to be greater than the normlised transverse diffusion coefficient for straight channel flows.
