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.
Nanowires are sensitive to changes in biological activities whereby their semiconductor channel surface picks up disparity in surface potential, which in turn modulates conductance of the channel.
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.
Furthermore, a smooth channel surface along with a wide pressure and temperature range make the chip suited for various applications.
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.
However, when the dimensions of the channel approach the mean free path that a molecule travels between collisions in the fluid, the continuum assumption begins to break down as interactions with the channel surface become more significant.
