Effect of intrinsic angular momentum in the capillary filling dynamics of viscous fluids

“…Scaling study of the capillary filling dynamics was revisited and new time scales were presented for the studied case. An increase in both spin and vortex viscosity was found to result in a decrease in the front position length of the moving liquid which is in agreement with the literature for the flow through a planar duct [34]. Three distinct regimes have also been demonstrated for the capillary filling dynamics.…”

“…2. This behavior was also observed for the channel flow where the fluid flow velocity increased by decreasing the spin viscosity[34].Moreover, as the viscosities increase the front position length results deviate more significantly from the no-angular-momentum (NAM) case. Increasing the channel height from 200 to 400 clearly increased the penetration depth.…”

Self-propulsion of a spherical electric or magnetic microbot in a polar viscous fluid

“…If realized, it may offer interesting technical application, for example in the transport of drugs through a fluid. The physical situation under consideration provides a remarkable example of the coupling of translational and rotational degrees of freedom in a fluid [6]- [9]. The spherical geometry poses a challenging problem and the mathematical solution has an interest of its own.…”
