Head-on collisions of dense granular jets
Jake Ellowitz
When a dense stream of dry, non-cohesive grains hits a fixed target, a collimated sheet is ejected from the impact region, very similar to what happens for a stream of water. In th…
Still water: dead zones and collimated ejecta from the impact of granular jets
Jake Ellowitz, Herve Turlier, Nicholas Guttenberg +2
When a dense granular jet hits a target, it forms a large dead zone and ejects a highly collimated conical sheet with a well-defined opening angle. Using experiments, simulations,…
Perfect fluid flow from granular jet impact
Jake Ellowitz, Nicholas Guttenberg, Wendy W. Zhang
Experiments on the impact of a densely-packed jet of non-cohesive grains onto a fixed target show that the impact produces an ejecta sheet comprised of particles in collimated moti…
Multi-Agent Reinforcement Learning and Genetic Policy Sharing
Jake Ellowitz
The effects of policy sharing between agents in a multi-agent dynamical system has not been studied extensively. I simulate a system of agents optimizing the same task using reinfo…
