Continuous Time Random Walks for the Evolution of Lagrangian Velocities
Marco Dentz, Peter K. Kang, Alessandro Comolli +2
We develop a continuous time random walk (CTRW) approach for the evolution of Lagrangian velocities in steady heterogeneous flows based on a stochastic relaxation process for the s…
Localized shear generates three-dimensional transport
Lachlan D. Smith, Murray Rudman, Daniel R. Lester +1
Understanding the mechanisms that control three-dimensional (3D) fluid transport is central to many processes including mixing, chemical reaction and biological activity. Here a no…
The Lagrangian Deformation Structure of Three-Dimensional Steady Flow
Daniel R. Lester, Marco Dentz, Tanguy Le Borgne +1
Fluid deformation and strain history are central to wide range of fluid mechanical phenomena ranging from fluid mixing and particle transport to stress development in complex fluid…
Chaotic Mixing in Three Dimensional Porous Media
Daniel R. Lester, Marco Dentz, Tanguy Le Borgne
Under steady flow conditions, the topological complexity inherent to all random 3D porous media imparts complicated flow and transport dynamics. It has been established that this c…
Hydrodynamic drift ratchet scalability
James Herringer, Daniel Lester, Graham E. Dorrington +2
The rectilinear "drift" of particles in a hydrodynamic drift ratchet arises from a combination of diffusive motion and particle-wall hydrodynamic interactions, and is therefore dep…
Fluid Stretching as a Levy Process
Marco Dentz, Daniel R. Lester, Tanguy Le Borgne +1
We study the relation between flow structure and fluid deformation in steady two-dimensional random flows. Beyond the linear (shear flow) and exponential (chaotic flow) elongation…
