Intrinsic speed characteristics of a self-propelled camphor disk under repulsive perturbations
Yuki Koyano, Jerzy Górecki, Hiroyuki Kitahata
Camphor is a well-studied material capable of generating self-propelled motion at a water surface, and the resulting dynamics can exhibit a wide range of behaviors. Here, we analyz…
Energetics-based model for a diffusiophoretic motion of a deformable droplet
Hiroyuki Kitahata, Yuki Koyano, Yasuaki Kobayashi +1
We construct a mathematical model for a diffusiophoretic motion of a deformable droplet, which is floating on a liquid surface and is driven by the surface tension gradient origina…
Modeling the time evolution of a camphor rotor perturbed by a stationary camphor source
Jerzy Gorecki, Yuki Koyano, Hiroyuki Kitahata
A self-propelled motion resulting from the dissipation of camphor molecules on the water surface has been attracting scientific attention for more than 200 years. A generally accep…
Simple mathematical model for a pairing-induced motion of active and passive particles
Hiroaki Ishikawa, Yuki Koyano, Hiroaki Ito +2
We propose a simple mathematical model that describes a pairing-induced motion of active and passive particles in a two-dimensional system, which is motivated by our previous paper…
