Experimental study of inertial particles clustering and settling in homogeneous turbulence
Alec J. Petersen, Lucia Baker, Filippo Coletti
We study experimentally the spatial distribution, settling, and interaction of sub-Kolmogorov inertial particles with homogeneous turbulence. Utilizing a zero-mean-flow air turbule…
Granular Impact: A Grain-scale Approach
Abram H. Clark, Alec Petersen, Lou Kondic +2
This work summarizes a series of studies on two-dimensional granular impact, where an intruding object strikes a granular material at high speed. Many previous studies on granular…
Nonlinear Force Propagation during Granular Impact
Abram H. Clark, Alec J. Petersen, Lou Kondic +1
We experimentally study nonlinear force propagation into granular material during impact from an intruder, and we explain our observations in terms of the nonlinear grain-scale for…
Collisional Model for Granular Impact Dynamics
Abram H. Clark, Alec J. Petersen, Robert P. Behringer
When an intruder strikes a granular material from above, the grains exert a stopping force which decelerates and stops the intruder. Many previous studies have used a macroscopic f…
