Aggregation in non-uniform systems with advection and localized source
Rishat R. Zagidullin, Alexander P. Smirnov, Sergey A. Matveev +2
We explore analytically and numerically agglomeration driven by advection and localized source. The system is inhomogeneous in one dimension, viz. along the direction of advection.…
Diffusion in a fluid flow generated by a source at the apex of a wedge
P. L. Krapivsky
We consider a particle diffusing inside a wedge with absorbing boundaries and driven by a radial flow of incompressible fluid generated by a source at the apex. The survival probab…
Non-extensive super-cluster states in aggregation with fragmentation
Nikolai V. Brilliantov, Wendy Otieno, P. L. Krapivsky
Systems evolving through aggregation and fragmentation may possess an intriguing super-cluster state (SCS). Clusters constituting this state are mostly large, so the SCS resembles…
Blast in a One-Dimensional Cold Gas: From Newtonian Dynamics to Hydrodynamics
Subhadip Chakraborti, Santhosh Ganapa, P. L. Krapivsky +1
A gas composed of a large number of atoms evolving according to Newtonian dynamics is often described by continuum hydrodynamics. Proving this rigorously is an outstanding open pro…
