This example uses the Granular Flow interface to model the fixed funnel method for calculating the angle of repose, where a funnel is kept at a fixed height. The funnel is first filled with grains which are subsequently released and collected as a heap. The resultant heap is then ... Mehr lesen
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. The reference analytical solution of incident irradiation is obtained with 256 discrete directions. Errors in ... Mehr lesen
This model demonstrates the filtration of grains of three different sizes as they pass through two vibrating sieves of different hole sizes. Mehr lesen
This model presents a way to compute projected area using the Surface-to-Surface Radiation interface of the Heat Transfer Module. By computing illuminated area from a set of directions on a discretized sphere, it is possible to interpolate the projected area onto any angle of incidence. ... Mehr lesen
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 ... Mehr lesen
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 ... Mehr lesen
Turbulent flow, Elliptic Blending R-ε interface is used to analyze fully developed turbulent flow in a spanwise rotating channel. Due to the influence of Coriolis force on turbulence, profiles of the flow variables are skewed at moderate rotation rate. The asymmetry between cyclonic ... Mehr lesen
Thermally induced transformations in solids may be modeled by using an Arrhenius law to express the dependence on temperature of the transformation rate. This tutorial model shows how to use the Irreversible Transformation subfeature, available under the Solid feature of the Heat ... Mehr lesen
The electrodes of a lithium-ion battery are porous, consisting of an active solid material, a binder, and pores filled with liquid electrolyte. If a force is applied on the porous layers of a battery, this will affect the volume fraction of the electrolyte-filled pores in the electrodes, ... Mehr lesen
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 ... Mehr lesen
