Particle motion in a spatially periodic flow

instability in a spatially periodic open flow

Laboratory experiments and numerical computations are conducted for plane channel flow with a streamwise-periodic array of cylinders. Well-ordered, globally stable flow states emerge from primary and secondary instabilities, in contrast with other wall-bounded shear flows, where instability generally leads directly to turbulence. A two-dimensional flow resembling TolhnienSchlichting waves arise...

Motion in a rocked ratchet with spatially periodic friction

We present a detailed study of the transport and energetics of a Brownian particle moving in a periodic potential in the presence of an adiabatic external periodic drive. The particle is considered to move in a medium with periodic space dependent friction with the same periodicity as that of the potential but with a phase lag. We obtain several results, most of them arising due to the medium b...

Periodic Particle Clustering in Narrow Channel Flow

This project involved a preliminary investigation of the periodic clustering of particles in narrow channels under thin film flow. Motivated by particle clustering in runoff after a storm, we constructed an experiment to observe particle clustering behavior. The particle size is comparable to channel width. The channel can be varied in width and angle of inclination. Flow rate can also be varie...
