Evolution of particle breakage studied using x-ray tomography and the discrete element method

EPJ Web of Conferences, 2017
Particle breakage can significantly change the fabric (size and shape of particles and contact network) of a granular material, affecting highly the material's macroscopic response.

Population balance modelling for a flow induced phase inversion based granulation in a two-dimensional rotating agglomerator

, 2011
A novel two-dimensional rotating agglomerator was developed to carry out the flow induced phase inversion (FIPI) based granulation. The process in this agglomerator shows that a continuous paste flow (mixed with liquid binder and primary particles) is ...

Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

Advanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Tensile Breakage of Particles in Granular Media

IOP Conference Series: Earth and Environmental Science
Abstract This paper proposes a method to assess the probability of breakage by tension of particles in a granular medium subjected to a triaxial stress state. It is considered that the resistant tensile stress and the intragranular acting one are random variables.

Feasibility of Nitrogen as a Carrier Gas for Inconel Cold Spray in Hydropower Application

Advanced Engineering Materials, EarlyView.
N2, despite being nearly two orders of magnitude cheaper than He, is a feasible carrier gas for cold spray Inconel coatings in hydropower repair applications when higher gas temperature and pressure are used. Reducing powder size significantly improved cavitation resistance, while the addition of fine chromium carbide particles further enhanced erosion
