Getting jammed in all directions: Dynamic shear jamming around a cylinder towed through a dense suspension
Olav Rømcke, Ivo R. Peters, R. Jason Hearst
Abstract
We study the propagation of dynamic jamming fronts in a dense cornstarch suspension generated by a towed body. Previous studies have investigated this phenomenon under pushing, pulling, or shearing, separately. In our experiment we are able to show how the front propagates in the full field surrounding the cylinder experiencing pushing, pulling, and shearing simultaneously. Though the fronts propagate symmetrically in the transverse direction to the cylinder movement, we observe a fore-aft asymmetry for the first time.
