View article: Conditional stability of particle alignment in finite-Reynolds-number channel flow
Conditional stability of particle alignment in finite-Reynolds-number channel flow Open
Finite-size neutrally buoyant particles in a channel flow are known to accumulate at specific equilibrium positions or spots in the channel cross-section if the flow inertia is finite at the particle scale. Experiments in different conduit…

View article: Separation of two attractive ferromagnetic ellipsoidal particles by hydrodynamic interactions under alternating magnetic field
Separation of two attractive ferromagnetic ellipsoidal particles by hydrodynamic interactions under alternating magnetic field Open
In applications where magnetic particles are used to detect and dose targeted molecules, it is of major importance to prevent particle clustering and aggregation during the capture stage in order to maximize the capture rate. Elongated fer…
