There are several different classifications of flow regimes that acquired based on early investigations, Newtonian fluid versus non-Newtonian fluid, ideal fluids versus actual fluids, one, two or three dimensional flow, viscous flow versus inviscid flow, internal flow versus external flow, laminar flow versus turbulent flow, steady flow versus unsteady flow and incompressible flow versus compressible flow, are some examples. In this study, a model mechanism is patterned after the available cases are in nature, like microorganisms, to investigate the capability of any motion in artificial self-swimming micro-mechanisms. With a little attention, it can be found that the micro-swimmer would swim in a low Reynolds number flow regime created by laminar, viscous and reversible flow conditions.
In current study, a combination of analytical and numerical solution has been used for feasibility of micro-swimmer motion. By coupling of the governing dynamical equations and Navier-Stokes equations, the position and velocity vectors of micro-swimmer are available and the trajectory can easily be obtained, too.
At the end, the translational and rotational position and velocity of the micro-swimmer are plotted in time in various conditions of control parameters. Also, the trajectory is obtained as the main characteristic of the micro-swimmer’s motion. It is obvious that all numerical cases of control parameters can’t be solved and just a few examples are investigated to some trends be shown.
