Self-assembly of self-propelled magnetic grains [PDF]
EPJ Web of Conferences, 2021 In this work, we study bidisperse mixtures of self-propelled magnetic particles of different shapes via discrete element method simulations. We show how these particles self-assemble into clusters and how these clusters depend on the ratio of the mixture, the magnetic interaction, and the shape of the grains.

Using the Impulse Method to Determine High-Pressure Dynamic Burning Rate of Solid Propellants
Aerospace, 2023 A new method for determining the burning rate of a solid propellant, called the Impulse Method, is proposed in this paper. It is based on the proportional relationship between the impulse generated and the mass of the burned propellant. The pressure–time
