This thesis is predominantly an experimental work, and its main objective is to study the physics of particle flow based on their shape in two industrial geometries, i.e., silo and dam-break. We use particles that are made of the same material and have similar volumes. In the case of the silo, we carry out experiments in quasi-2D, mono-layer, and 3D setups. In the case of a granular dam break, we perform both experiments and simulations in a quasi-2D rectangular setup. Since we investigate the physics of the flow, we mainly investigate the particle velocity, volume fraction, and orientation.
