Hydrodynamical random walker with chemotactic memory
H. Mohammady, B. Esckandariun, A. Najafi
A three-dimensional hydrodynamical model for a micro random walker is combined with the idea of chemotactic signaling network of E. coli. Diffusion exponents, orientational correla…
Rectified motion in an asymmetric channel: the role of hydrodynamic interactions with walls
B. Golshaei, A. Najafi
Dynamics of a Brownian particle in an asymmetric micro-channel that is subjected to an external oscillating force is numerically analyzed. In addition to the elastic collisions wit…
Entropic forces exerted on a rough wall by a grafted semiflexible polymer
Parvin Bayati, Leila Ghassab, Ali Najafi
We study the entropic force due to a fluctuating semiflexible polymer that is grafted from one end and confined by a rigid and rough wall from the other end. We show how roughness…
Rheological properties of a dilute suspension of self-propelled particles
Moslem Moradi, Ali Najafi
With a detail microscopic model for a self-propelled swimmer, we derive the rheological properties of a dilute suspension of such particles at small Peclet numbers. It is shown tha…
