    • DEM particle characterization by artificial neural networks and macroscopic experiments 

      Benvenuti, Luca; Kloss, Christoph; Pirker, Stefan (CIMNE, 2015)
      Conference report
      Open Access
      The macroscopic simulation results in Discrete Element Method (DEM) simulations are determined by particle-particle contact laws. These usually depend on semi-empirical parameters, difficult to obtain by direct microscopic ...
    • Determining the coefficient of friction by shear tester simulation 

      Aigner, Andreas; Schneiderbauer, Simon; Kloss, Christoph; Pirker, Stefan (CIMNE, 2013)
      Conference report
      Open Access
      The flow behaviour of very dense particle regimes such as in a moving or fluidized bed is highly dependent on the inter-particle friction, which can be characterized by the coefficient of friction. Since only rough guide values ...
    • Identification of block-like movement in cohesive and non-cohesive spouted bed operations 

      Vila, Alija; Lichtenegger, Thomas; Puttinger, Stefan; Pirker, Stefan (CIMNE, 2017)
      Conference report
      Open Access
      Spouted beds are widely used in the chemical and process industries for a large variety of processes. Good understanding of the transport phenomena in these systems is of great importance to improve the design and scale-up ...
    • Pattern formation in laminar flow of suspensions through square channels 

      Seil, Philippe; Pirker, Stefan; Lichtenegger, Thomas (CIMNE, 2017)
      Conference report
      Open Access
      The study of particulate suspensions flowing through narrow channels has received much attention in the last decades, especially with advance in the field of microfluidics devices. In square channels, it is known that particles ...
