Buoyancy and Stability for Submerged and Floating Bodies

3.6K
In fluid mechanics, buoyancy and stability are key concepts for understanding the behavior of submerged and floating bodies. When a stationary body is fully or partially submerged in a fluid, the fluid exerts a force on the body known as the buoyant force. This force acts vertically upward through a point called the center of buoyancy, which is the center of the displaced fluid volume. According to Archimedes' principle, the magnitude of the buoyant force is equal to the weight of the fluid...

Summary
This summary is machine-generated.

We studied deformable microswimmers in swirl flow, finding that swimmers elongating parallel to propulsion can escape vortices. This offers a strategy for designing artificial microswimmers for complex flows.

Area of Science:

  • Fluid dynamics
  • Active matter physics
  • Microhydrodynamics

Background:

  • Classical Kepler and Rutherford problems provide foundational insights into orbital mechanics.
  • Active microswimmers exhibit complex behaviors in fluid environments.
  • Understanding microswimmer dynamics in vortical flows is crucial for designing micro-robots and understanding biological systems.

Purpose of the Study:

  • To investigate the behavior and dynamics of deformable microswimmers in a swirl flow.
  • To identify and analyze the stability of steady bound states.
  • To study the capturing and scattering dynamics of microswimmers approaching a vortex center.

Main Methods:

  • Theoretical investigation of deformable microswimmer dynamics in a swirl flow.
  • Analysis of steady bound states and their stability.
  • Simulation of swimmer trajectories and classification based on elongation behavior.

Main Results:

  • Identification of novel steady bound states in swirl flow.
  • Observation of distinct capturing and scattering dynamics for different swimmer types.
  • Swimmers elongating perpendicularly to propulsion can be captured, while those elongating parallel are scattered.

Conclusions:

  • The elongation strategy of microswimmers significantly influences their interaction with swirl flows.
  • Parallel elongation offers a promising escape strategy from vortex centers.
  • Findings provide a basis for designing artificial microswimmers with controllable behavior in complex flows.
  • Experimental verification using self-propelled droplets is feasible.
