A pore-scale study on the drying kinetics and mechanical behavior of particle aggregates

Pham, T. S.; Chareyre, B.; Tsotsas, E.; Kharaghani, A. (Editorial Universitat Politècnica de València, 2018-09-07)

[EN] A discrete thermo-mechanical drying model is developed to investigate the interaction between the porous structure and the drying characteristics of dense particle aggregates. The solid phase consists of polydisperse ...
An energy consistent frictional dissipating algorithm for particle contact problems

Bravo Pareja, Rafael; Pérez-Aparicio, José L.; Laursen, T.A. (Wiley, 2012-11-30)

An energy frictional dissipating algorithm (EFDA) for time integration of Coulomb frictional impact-contact problems is presented. With the use of the penalty method, and in the context of a conserving framework, linear ...
Analytical and discrete solutions for the incipient motion of ellipsoidal sediment particles

Bravo, Rafael; Ortiz, Pablo; Pérez-Aparicio, José L. (Taylor & Francis, 2018)

[EN] This work introduces analytical and numerical approaches to compute the incipient motion of ellipsoidal sediment particles. Initiation of motion of spherical particles is dominated by rolling mode. However, solutions ...
In Silico Hemodynamics and Filtering Evaluation of a Commercial Embolic Protection Device

Gil Megías, Antonio; Quintero-Igeño, Pedro-Manuel; Mares, Andrea; Serra, Juan; Sánchez-Nevárez, Manuel Ignacio; Miralles, Manuel (Springer-Verlag, 2021-09)

[EN] During the last years, several kinds of Embolic Protection Devices (EPD) have been developed, with the aim of minimizing complication caused by thrombi generated during Carotid Artery Stenting (CAS). These devices are ...
Incipient sediment transport for non-cohesive landforms by the discrete element method (DEM)

Bravo, R.; Ortiz Rossini, Pablo; Pérez Aparicio, José Luis (Elsevier, 2014-02-15)

[EN] We introduce a numerical method for incipient sediment transport past bedforms. The approach is based on the discrete element method (DEM) [1], simulating the micro-mechanics of the landform as an aggregate of rigid ...
