Abstract (EN):
A new experimental setup for the study of the complex flow dynamics around 3D microbot prototypes
in a straight microchannel has been developed and assessed. The ultimate aim of this work is focused
on the analysis of the morphology of different microbot prototypes to get a better insight into their
efficiency when they swim through the main conduits of the human circulatory system. The setup
consists of a fused silica straight microchannel with a 3D microbot prototype fastened in the center of
the channel cross-section by an extremely thin support. Four different prototypes were considered: a
cube, a sphere and two ellipsoids with aspect ratios of 1 : 2 and 1 : 4, respectively. Flow visualization and
micro-particle image velocimetry (mPIV) measurements were performed using Newtonian and viscoelastic
blood analogue fluids. An efficiency parameter, I, to discriminate the prototypes in terms of flow
disturbance has been proposed.
