Granular mixing and flow dynamics in horizontal stirred bed reactors
Sahar Pourandi, Igor Ostanin, Thomas Weinhart
Horizontal stirred bed reactors (HSBRs) are used in gas--phase polyolefin production, where efficient solids mixing and controlled residence time distributions are essential for pr…
Modeling Complex Multiphysics Systems with Discrete Element Method Enriched with the Kernel-Independent Fast Multipole Method
Igor A. Ostanin
The paper describes the coupling of the MercuryDPM discrete element method (DEM) code and the implementation of the kernel-independent fast multipole method (KIFMM). The combined s…
Calibration of a DEM contact model for wet industrial granular materials
Sahar Pourandi, P. Christian van der Sande, Igor A. Ostanin +1
This study presents and calibrates a Discrete Element Method (DEM) contact model for wet granular materials in the pendular regime. The model extends a previously calibrated dry co…
Arbitrary Controlled Re-Orientation of a Spinning Body by Evolving its Tensor of Inertia
Igor Ostanin, Matthias Sperl
Bodies with the nonspherical tensor of inertia exhibit a variety of rotational motion patterns, including chaotic motion, stable periodic (quasi-periodic) rotation, unstable rotati…
Atomistic mechanism of friction force independence on the normal load and other friction laws for dynamic structural superlubricity
Nikolay V. Brilliantov, Alexey A. Tsukanov, Artem K. Grebenko +2
We explore dynamic structural superlubricity for the case of a relatively large contact area, where the friction force is proportional to the area (exceeding ) expe…
Rigid Clumps in the MercuryDPM Particle Dynamics Code
Igor Ostanin, Vasileios Angelidakis, Timo Plath +3
Discrete particle simulations have become the standard in science and industrial applications exploring the properties of particulate systems. Most of such simulations rely on the…
