Inertia-Induced Synchronization of Undulatory Swimming

چکیده
The ubiquitous cooperative locomotion in a fluid has long been considered to gain evolutionary advantages by increasing the efficiency of living creatures. Synchronization between undulatory swimmers, such as spermatozoa and eels at low high Reynolds numbers respectively, attracted much attention for its theoretical importance dynamics. Such swimmers propel themselves generating travelling waves along their bodies or flagella. To understand hydrodynamic interaction waving motions, we numerically analytically study infinite 2D waving-sheet model introduced Taylor using method perturbation on basis small amplitude [1]. Previous studies have shown that zero number, two sheets swimming close one another do not preferred phase difference Newtonian However, will reach stable in-phase synchronized state under influence elastic effect, either form swimmer body viscoelastic [2,3]. Since inertia effects is negligible larger synchronizing behavior finite number. Our analysis show would eventually an anti-phase configuration, which contrast with previous studies. Propulsion velocity time evolution are also studied across different parameters, showing number decreasing distance can reduce final synchronization. speed increases through synchronizing, compared individual swimming. By performing numerical simulations arbitrary amplitudes, find above critical separation h sheets, maximum h, consistent prediction. Below distance, decreases indicating there exists optimum reaching fastest

Undulatory and Flagellar Swimming
SYNOPSIS. We present a mathematical model and numerical method designed to study the fluid dynamics of swimming organisms. The full Navier-Stokes equations are solved in a domain of fluid within which an organism undergoing time-dependent motions is immersed. Of interest are both the dynamics of a single organism and the relationship of its morphology to its motility properties, as well as the ...
متن کاملUndulatory swimming in viscoelastic fluids.
The effects of fluid elasticity on the swimming behavior of the nematode Caenorhabditis elegans are experimentally investigated by tracking the nematode's motion and measuring the corresponding velocity fields. We find that fluid elasticity hinders self-propulsion. Compared to Newtonian solutions, fluid elasticity leads to up to 35% slower propulsion. Furthermore, self-propulsion decreases as e...
متن کاملUndulatory swimming in non-Newtonian fluids
We numerically investigate the effects of non-Newtonian fluid properties, including shear thinning and elasticity, on the locomotion of Taylor’s swimming sheet with arbitrary amplitude. Our results show that elasticity hinders the swimming speed, but a shear-thinning viscosity in the absence of elasticity enhances the speed. The combination of the two effects, modelled using a Giesekus constitu...
متن کاملMechanics of Undulatory Swimming in a Frictional Fluid
The sandfish lizard (Scincus scincus) swims within granular media (sand) using axial body undulations to propel itself without the use of limbs. In previous work we predicted average swimming speed by developing a numerical simulation that incorporated experimentally measured biological kinematics into a multibody sandfish model. The model was coupled to an experimentally validated soft sphere ...
