  Experimental results of towing a cylinder through a dense suspension of
cornstarch and sucrose-water are presented. Focus is placed on the jamming
fronts that exist in such systems. The literature has concentrated on the
propagation of the jammed region under pushing, pulling or shearing conditions
independently. How the different fronts interact and if the fronts are
symmetric when generated simultaneously has remained unexplored. Investigating
this is our main goal. With the current setup, we are able to view a
continuous, quasi-2D field around the cylinder. As such, a new way of
generating jamming fronts is presented whereby pushing, pulling and shearing
can be examined simultaneously. In agreement with previous studies, the front
propagates roughly twice as fast in the longitudinal direction compared to the
transverse direction, which is attributed to a single underlying onset strain,
regardless of orientation from the cylinder. Although the jamming front shows
nearly perfect transverse symmetry, there is clear longitudinal asymmetry. This
is evident in the velocity and strain fields, and is also detectable in the
front propagation velocity and onset strain.
