This study presents a two-stage discrete element method (DEM) simulation of thermal conduction in compressed granular materials. In the first stage, a granular bed composed of spherical grains is mechanically compacted by applying a constant pressure of 20 kPa through a downward moving ... En savoir plus
A ribbon mixer (sometimes referred to as a ribbon blender) is a mechanical device that is commonly used to mix different types of granular material. Ribbon mixers are widely used across various industries including food processing, pharmaceuticals, chemical industries, agriculture, ... En savoir plus
This model is used on "Heat Transfer with Radiation in Participating Media and the Discrete Ordinates Method" to compare quadrature sets used in the method of discrete ordinates. To assess the performance of quadrature sets in complex geometries, results of incident irradiation and ... En savoir plus
This example demonstrates the usage of the Scattered Field formulation to compute the scattering of light off of a single scatterer on top of a dielectric half-space. It uses the analytic Fresnel equations to design the background field. For a detailed introduction to this model, see ... En savoir plus
This model uses the Granular Flow and Membrane interfaces to simulate the packing of spherical grains in a flexible container, a procedure often found in the processing industry. In this example, grains are packed into a cubic container constructed of a thin polymer fabric. Two packing ... En savoir plus
This model shows how to simulate moisture redistribution inside a wall with capillary active interior insulation. The wall consists of three layers: brick, mortar and insulating material. At the beginning of simulation, there is a sudden change in vapor pressure and temperature at ... En savoir plus
The miniaturization of electronics devices requires batteries with higher energy density and power. To increase the contact area between the electrodes and the solid electrolyte, 3D configurations such as the trench geometry are used. This example demonstrates how to model a solid-state ...
