appliion of discrete element method for simulating feeding

2016/5/5QUANTUM WALKS: THEORY, APPLICATION, AND IMPLEMENTATION by Albert Thomas Schmitz Bachelor of Science, Bemidji State University, 2011 A thesis submitted to the Graduate Faculty of the University of North Dakota in partial ful llment of the It proves challenging to analyze the particle dynamics experimentally, particularly in a multiphase microreactor. A numerical model based on volume of fluid (VOF) coupled with discrete element method (DEM) is developed to investigate the particle dynamics in the liquid slugs of a gas–liquid–solid Taylor flow microreactor. The detailed implementation of the coupling and numerical schemes is

Simulating large-scale problems are still challenging for discontinuous deformation analysis (DDA). To this end, this paper develops an efficient disk-based DDA (DDDA) model considering the efficiency in searching contact pairs and solving linear equations. First, an

Systolic blood flow has been simulated in the abdominal aorta and the superior mesenteric artery. The simulations were carried out using two different computational hemodynamic methods: the finite element method to solve the Navier Stokes equations and the lattice Boltzmann method. We have validated the lattice Boltzmann method for systolic flows by comparing the velocity and pressure profiles

2008/11/20Compared to the IB methods described in [8, 11, 12], our method can be used for simulating dynamics of linearly elastic or viscoelastic solids as well as flow-induced deformation of such solids. The FSI solver is also designed to solve two- as well as three-dimensional problems and is therefore very well suited for high-fidelity modeling of biological configurations.

The ability to model comminution techniques has been key in the mineral processing industry and other industries where size reduction of rocks is a key focus. With the need for more accurate and sophisticated models, the introduction of computational models like the discrete element method (DEM) has started to solve some of the complex problems in comminution. This review article provides a

element method is by far the most widely used and versatile technique for simulating deformable solids. This chapter gives a brief overview of the finite element method, with a view to providing the background needed to run simple simulations using a commercial

A method for feeding an animal using the feeding system is also provided herein. Type: Grant Filed: June 18, 2014 The method includes simulating an experience of teaching the animal the behavior in a virtual training environment using the optimal training

Discrete Element Method (DEM) is used to simulate particle flow. Particles are everywhere around us: Dirt, sand, pebbles, grains, hay, minerals, ores, manufactured materials like tablets, powders, etc. DEM is about modeling behavior of particles of different

2009/4/2It can be seen as an application of the partition of unity concept to the s-version of the finite element method []. A similar approach has been recently proposed for GFEM by Duarte and Kim [ 36 ]. XFEM has recently been applied to concurrent continuum-atomistic simulations of cracks and dislocations by Gracie and Belytschko [ 48 ].
