Taylor Dispersion in Sedimentation of an Axisymmetric Brownian Particle with Centre Offset
Zhongqiang Xiong, Ryohei Seto, Masao Doi
When a non-spherical particle sediments, its velocity generally changes in time as the particle orientation changes in time. This gives extra dispersion of the particle position in…

Brownian motion of a rod threading through a ring with fixed ring-center
Zhongqiang Xiong, Shigeyuki Komura, Masao Doi
We study the Brownian motion of a rigid rod threading through a small fixed ring while the ring can freely rotate. We derive the distribution function for the sliding displacement…
