ow in the center channels (6, 7) followed by the outermost channels (1, 12).
Pressure and velocity vector plots show considerable turbulence mixing and
ow separation in the feeder near the ow channel inlets. Also, there is a
strong impingement of the ow near the inlet of the channel, especially near
the center channels. As the ow approaches the outer channels, there is con-
version of dynamic head into static pressure and this contributed toward
an increased ow in the outermost channels. In general, results show non
uniform distribution of mass ow rates in the channels. Similar results are
also obtained for all other ca ...
