Chemical Reactions and Soot Build-Up in a Diesel Filter

In this tutorial, a filter system for a diesel engine is modeled, including a soot layer development and oxidization. The build-up of the layer is held in check by both catalytic and non-catalytic reactions, where carbon is oxidized to carbon monoxide and carbon dioxide, which in turn ... Mehr lesen

Luneburg Lens

A Luneburg lens is a type of graded index, or GRIN lens, in which the gradient of the refractive index leads to special focusing properties. This example model uses the Geometrical Optics interface to compute the curved ray trajectories in the graded-index medium. Mehr lesen

Capacitively Coupled Plasma

The NIST Gaseous Electronics Conference has provided a platform for studying Capacitively Coupled Plasma (CCP) reactors, which is what this application is based upon. The operating principle of a capacitively coupled plasma is different when compared to the inductive case. In a CCP ... Mehr lesen

Study of a Defective Microstrip Line via Frequency-to-Time FFT Analysis

While transient analyses are useful for time domain reflectometry (TDR) to handle signal integrity (SI) problems, many RF and microwave examples are addressed using frequency domain simulations generating S-parameters. However, from the frequency domain data it is difficult to identify ... Mehr lesen

Coupled Analysis of Flow and Stress in a Pipe

In this tutorial model, the flow in a pipe with a bend is computed using the Pipe Flow interface. The computed fluid load is used as input to a stress analysis in the Pipe Mechanics interface. Gravity loads from the pipe and fluid are also taken into account. Mehr lesen

Silicon–Graphite-Blended Electrode with Thermodynamic Voltage Hysteresis

Due to its high capacity, silicon (Si) is often added to graphite in the negative electrode of lithium-ion batteries. Silicon–graphite blended electrodes may exhibit significant thermodynamic voltage hysteresis (“path dependence”) because the equilibrium potential of the lithium–silicon ... Mehr lesen

Crevice Corrosion of Iron in an Acetic Acid/Sodium Acetate Solution

Mass transport limitations within thin crevices can often result in the local electrochemistry to differ significantly between the crevice opening (mouth) and end (tip), and as a result of the differences in local chemistry, corrosion may occur. This example models crevice corrosion of ... Mehr lesen

Jelly Roll Using a Flattened Geometry

This example replicates the results of the Jelly Roll tutorial example using a flattened representation of the wound spiral-based geometry. See that model entry for details on the background, original geometry, materials, and the general physics setup. Mapping the original problem to a ... Mehr lesen

Viscoelastic Flow Through a Channel with a Flexible Wall

This model represents a test case of a flow in an elastic tube which is present in several applications. This specific case models viscoelastic flow and represents steady flow in a channel in which part of the upper wall is replaced by an elastic plate subjected to an external pressure. ... Mehr lesen

Duct with Right-Angled Bend

In this tutorial the acoustic behavior of a duct or waveguide with a right angled bend is analyzed. The model uses port boundary conditions at the inlet and outlet. The ports can capture and treat non-plane propagating modes in waveguides, extending the analysis above the first cutoff ... Mehr lesen
