    • 3D laser scanning technique coupled with DEM GPU simulations for railway ballasts 

      Pizette, Patrick; Govender, Nicolin; Wilke, Daniel N.; Gobe, Benjamin; Abriak, Nor-Edine; Rajamani, Raj K. (CIMNE, 2017)
      Conference report
      Open Access
      Spheres with complex contact models or clumped sphere models are classically used to model ballast for railway applications with the Discrete Element Method (DEM). These simplifications omits the angularity of the actual ...
    • Effect of wall roughness on interface behavior of DEM-simulated granular material 

      El Cheikh, Khadiija A.; Rémond, Sébastien; Djelal, Chafika; Pizette, Patrick; Vanhove, Yannick (CIMNE, 2015)
      Conference report
      Open Access
      This paper deals with the behavior of packed spherical particles sheared on rough surfaces. The discrete element method (DEM) is used to model the granular material. Likewise, the roughness is modeled by spherical boundary ...
    • Numerical study on the effect of particle shape on mixers 

      Govender, Nicolin; Wilke, Daniel M.; Rajamani, Raj K.; Pizette, Patrick; Khinast, Johannes; Glasser, Benjamin J. (CIMNE, 2017)
      Conference report
      Open Access
      Homogenization of particulate systems is a critical part in the processing of particulate materials to achieve consistency and ensure product quality. Homogenization is achieved by mixing, the aim is to obtain a final mixture ...
    • Potential for interactive design simulations in discrete element modelling 

      Wilke, Daniel N.; Govender, Nicolin; Pizette, Patrick; Rajamani, Raj K. (CIMNE, 2017)
      Conference report
      Open Access
      This study investigates the potential for combining lower fidelity models with high performance solution strategies such as efficient graphical processing unit (GPU) based discrete element modelling (DEM) to not only do ...
    • Validation of the gpu based blaze-dem framework for hopper discharge 

      Govender, Nicolin; Pizette, Patrick; Wilke, Daniel N; Abriak, Nor-edine (CIMNE, 2015)
      Conference report
      Open Access
      Understanding the dynamical behavior of particulate materials is extremely important to many industrial processes, with typical applications that range from hopper flows in agriculture to tumbling mills in the mining ...
