Query: Electrothermally Modulated Dispersion in Viscoelastic Fluids on
  Patterned Surfaces   Augmenting the dispersion of a solute species remains a challenging topic in
electroosmotically-actuated flows due to the inherent plug-like feature of its
velocity profile. In this study, we improvise on electrothermal flow of
viscoelastic fluids through a parallel-plate microchannel with patterned
surface charge to depict augmented dispersion coefficient of a solute. Here we
consider the physical properties of the fluid to be temperature-dependent,
thus, bringing out the combinatorial effect of both the thermal perturbation as
well as the surface modulation on the resulting dynamics. This analysis unveils
that by making a judicious choice of pertinent parameters one can control the
flow rate with the desired account of dispersion. We envisage that the
intricate coupling between the electrothermal perturbation and surface charge
modulation combined with the fluid rheology may have tremendous implications
towards the efficient designing of microfluidic devices.
