Abstract

In this work discrete element modeling (DEM) was applied to the flow of granular jets against a target. The resulting sheetlike or conelike formations under different conditions are described and explained by means of kinetic analysis. A qualitative and quantitative comparison with experimental results [Cheng et al., Phys. Rev. Lett. 93, 188001 (2007)] provides interesting insights in the theoretical treatment of the head-on collision of granular jets. Results presented in this paper provide a theoretical description of this type of physical system. However, there still exist obstacles in obtaining quantitative results.
