Prediction of random packing density and flowability for non-spherical particles by deep convolutional neural networks and Discrete Element Method simulations

R Hesse, F Krull, S Antonyuk - Powder Technology, 2021 - Elsevier
Non-spherical particles can be found in many industrial processes. Unfortunately, scalar
shape parameters are often insufficient to predict their complex behavior. Therefore, this …
