When processing aids such as slip additives migrate towards the wall they form a thin film of low viscosity between the flow
channel surface and the polymer melt.
Once the saturation of the depletion region is reached, additional gate voltage will entice negative mobile electrons to the
channel surface [20].
Since the wall temperature varies along the channel, for initial conditions of the simulation was used not the wall temperature, but the heat flow for
channel surface area.
Figure 5 presents the current density of the DGA nMOSFETs at the
channel surface when the gate, source, drain, and body voltages were 3.3 V, 0 V, 0.05 V, and 0 V, respectively.
This is a considerable drawback in Microfluidics application since it renders the surface lacking in wettability with aqueous solvents and offers a
channel surface prone to trapping air bubbles.
Also, according to the company, the extremely smooth
channel surface, in combination with a wide pressure and temperature range make it ideal for a broad range of applications.
The producing aggregates from the
channel surface was most likely the potential factor for this substantial increase as the aggregate size was comparatively large compared to the width of the channel.
We seek a numerical solution to Equation (13) that is stiff because the functions representing VDW and EDL forces are rapidly varying, especially in the vicinity of the
channel surface. Also, as the range of integration of the functions extends from [H.sub.0] = 0.001 to [H.sub.[infinity]] = 100, the mesh size used for the finite difference approximation should be varying with smaller mesh sizes near to the
channel surface and larger mesh sizes towards the bulk stream.
