This model shows how a flow model can be coupled to a process control mechanism. Controlling application parameters according to other application parameters is important within process engineering. Most control mechanisms use the data at a wall or an outlet to control inlet ... En savoir plus
Modeling the electrical activity in cardiac tissue is an important step in understanding the patterns of contractions and dilations in the heart. The heart produces rhythmic electrical pulses, which trigger the mechanical contractions of the muscle. A number of heart conditions involve ... En savoir plus
In this first half of a two-part example, a 2D model of a trench-gate IGBT is built, which will be extended to 3D in the second half. In general, it is the most efficient to start with a 2D model to make sure everything works as expected, before extending it to 3D. The Caughey&ndash ... En savoir plus
Chain drives are used for transmitting power from one shaft to another, located at some distance. This example demonstrates how to model a chain sprocket assembly in 3D. The geometry consists of a roller chain wrapped around two sprockets. All components are assumed to be elastic. The ... En savoir plus
The S-N curve, also called the Wöhler curve, is one of the most popular methods for fatigue evaluation. The curve relates stress amplitude to the limiting fatigue life and can be obtained directly from a set of standard fatigue test. Many times our applications are subjected to ... En savoir plus
Removing halogen groups from hydrocarbons is an important reaction step in several chemical processes. One application is water purification. Other examples involve organic synthesis, where the removal of halogen groups serves as a starting point for carbon-carbon coupling reactions. ... En savoir plus
The incompressible boundary layer on a flat plate in the absence of a pressure gradient is usually referred to as the Blasius boundary layer. The steady, laminar boundary layer developing downstream of the leading edge eventually becomes unstable to Tollmien-Schlichting waves and finally ... En savoir plus
Transport through porous structures is usually treated using simplified homogeneous models with effective transport properties. This is in most cases a necessity, since the typical dimensions of the pores and particles making up the porous structure are several orders of magnitude ... En savoir plus
1D model of a thermal energy storage (TES) system consisting of a packed bed of pellets. Three approaches for heat transfer in porous media are compared: A one-equation local thermal equilibrium (LTE) model A two-equations local thermal nonequilibrium (LTNE) model A multiscale ... En savoir plus
Passive devices can be designed using lumped element features if both the operating frequency of the device and the insertion loss of lumped elements are low. This example simulates two types of lumped element filters that are similar to lumped ports, except that they are strictly ... En savoir plus
