Abstract
The flow of granular materials is critical to a wide variety of industrial processes. However, the influence of boundary conditions on the parameters of the gravitational flow of granular materials underlying granular flows is poorly understood.
The aim of this work is to study the influence of boundary conditions on the slope (substrate material and its roughness) on the parameters of the gravitational flow of the material, determined by the equation of state of the granular medium. In the course of the study, the equations of state of the granular medium were determined and the primary influence on the relationship between the dilatancy and the "temperature" of the granular medium was established, which affects the degree of its roughness.
