abstract = {Fluid flow along microchannels can be induced by keeping
opposite walls at different temperatures and placing
elongated tilted pillars inside the channel. The driving
force for this fluid motion arises from the anisotropic
thermophoretic effect of the elongated pillars that
generates a force parallel to the walls and perpendicular to
the temperature gradient. The force is not determined by the
thermophilic or thermophobic character of the obstacle
surface, but by the geometry and the thermophoretic
anisotropy of the obstacle. Via mesoscale hydrodynamic
simulations, we investigate the pumping properties of the
device as a function of the channel geometry and pillar
surface properties. Applications as fluidic mixers and fluid
alternators are also outlined, together with the potential
use of all these devices to harvest waste heat energy.
Furthermore, similar devices can also be built employing
diffusiophoresis or electrophoresis.},
