Query: Hydrodynamic Impedance Correction for Reduced-Order Modeling and
  Real-Time Control of Spermatozoa-Like Soft Micro-Robots for Medicine   Hydrodynamic interactions play a key role in the swimming behavior and power
consumption of bio-inspired and bio-mimetic micro-swimmers, Cybernetic or
artificial alike. As micro-robotic devices, bio-inspired micro-swimmers require
fast and reliable numerical models for robust control in order to carry out
demanding therapeutic tasks as envisaged for more than sixty years. The fastest
known numerical model, the resistive force theory (RFT), incorporates local
viscous force coefficients with the local velocity of slender bodies in order
to find the resisting hydrodynamic forces, however, omitting the induced far
field altogether. In this scheme, the forces are calculated for a pure fluid
resistance, however, at the expense of time-dependent hydrodynamic interaction
effects. As a result, the power requirement cannot be predicted accurately
although the supply of necessary power is one of the biggest obstacles impeding
the micro-robotic efforts. In this study, an analysis strategy is proposed to
improve the RFT-based analysis, particularly for spermatozoa and
spermatozoa-inspired micro-swimmers with elastic slender tails, in order to
present a practical solution to the problem. The required analytical correction
and the necessary correction coefficients are based on hydrodynamic impedance
analysis via intensive computational fluid dynamics (CFD) models, i.e., the
time-dependent solution of 3-dimensional Navier-Stokes equations incorporated
with deforming mesh and subject to conservation of mass. The CFD-based model
results are then used to extract the correction coefficients with the help of a
cost function written based on the hydrodynamic power required to sustain the
continuous swimming of selected shape and design. The performance of the
corrections embedded in the RFT model is finally validated against the CFD
model by means of hydrodynamic power comparisons.
