We believe that both strategies for reducing the cells speed are interesting and both show advantages and disadvantages: (i) changing the geometry is very simple in the fabrication step; however it leads to a nonperfect straight trajectory of the cells; (ii) acting on the viscosity of the liquid could be not always possible; however, it permits working with a narrowed confined flow
and thus a deterministic path of the cells.
For that purpose, let us consider a confined flow
of Non-Newtonian power-law fluid around a heated square cylinder in a two-dimensional vertical channel.
During die filling (the next step), flowability remains important, both flow induced by gravity and more confined flow
as the feeder forces powder into the die.
During die filling (the next step), flowability remains important; both flow into the empty die and confined flow
as the die fills.
In spite of its complexity, HMAC noise can be analysed as two main types of noise sources: the centrifugal fan noise and the noise generated in the confined flow
10 and 11 suggest that, as the polymer temperature reduces, the zone with temperature above [T.sub.g] reduces, thus resulting in a more confined flow
field near the polymer-cutter contact, i.e.
considered cases of confined flow
in a channel with high vertical sidewalls and unconfined flow with a floodplain.
