dc.description.abstract | That surface roughness has an effect on fluid flow in
networks has been understood for well over a century. The
exact effect roughness has on fluid flow has not been
completely understood, but a working estimate has been offered
by a variety of authors over time. The work of Colebrook,
Nikuradse, and Moody has provided practitioners with a
method to include at least a first order estimate of roughness
effects, but their work has been limited to relative roughness to
diameter values of 5% or less. Modern fluidic systems at the
mini and micro levels routinely violate the 5% relative
roughness threshold due to the inability to control the
roughness of surfaces to sufficient levels with respect to
decreasing system scale. Current work by Kandlikar, et al., has
extended the traditional methods of assessing surface roughness
effects up to 14% relative roughness by including the effect of
constricted flow diameters and modifying the Moody diagram
to reflect new experimental data. The future of micro fluidics
would suggest that trends for miniaturization will continue and
that further understanding and experimentation will be
warranted. This is especially true with regards to
understanding the role of roughness on the flow in mini and
micro channels. | en_US |
