Maximum Angle of Stability of a Wet Granular Pile
Sarah Nowak, Azadeh Samadani, Arshad Kudrolli
Anyone who has built a sandcastle recognizes that the addition of liquid to granular materials increases their stability. However, measurements of this increased stability often co…
Shocks in sand flowing in a silo
Azadeh Samadani, L. Mahadevan, A. Kudrolli
We study the formation of shocks on the surface of a granular material draining through an orifice at the bottom of a quasi-two dimensional silo. At high flow rates, the surface is…
Angle of repose and segregation in cohesive granular matter
Azadeh Samadani, A. Kudrolli
We study the effect of fluids on the angle of repose and the segregation of granular matter poured into a silo. The experiments are conducted in two regimes where: (i) the volume f…
Swarming ring patterns in bacterial colonies exposed to ultraviolet radiation
Anna M. Delprato, Azadeh Samadani, A. Kudrolli +1
We report a novel morphological transition in a Bacillus subtilis colony initially growing under ambient conditions, after ultraviolet radiation exposure. The bacteria in the centr…
