Piezoelectric valves are frequently employed in medical and laboratory applications due to their fast response times and quiet operation. Their energy efficient operation, also dissipates little heat, which is often important for these applications. This model shows how to model a ... Mehr lesen
In this example, three parallel pipelines of length 68 km and a horizontal separation distance of 10 m between them are protected against corrosion by an impressed current cathodic protection (ICCP) system using a series of anodes. Each anode is connected to all three pipelines, ... Mehr lesen
During an internal short circuit of a battery, the two electrode materials are internally and electronically interconnected, giving rise to high local current densities. Internal short circuits may occur in a lithium-ion battery due to, for instance, lithium dendrite formation or a ... Mehr lesen
This tutorial demonstrates the use of the density-gradient formulation to include the effect of quantum confinement in the device physics simulation of a silicon inversion layer. This formulation requires only a moderate increase of computational resources as compared to the conventional ... Mehr lesen
The Yagi–Uda antenna is designed for a specific Wi-Fi band and can reduce eavesdropping by directing signals with the help of directors. This antenna consists of one uniformly spaced reflector and four directors. Simulated results show a maximum 10 dBi gain and a front-to-back ratio of ... Mehr lesen
The goal with this app is to explain experimental electrochemical impedance spectroscopy (EIS) measurements and to show how you can use a simulation app, along with measurements, to estimate the properties of lithium-ion batteries. The app takes measurements from an EIS experiment and ... Mehr lesen
This example models the desalination of water by capacitive deionization in a "flow-between" cell (fbCDI). The model geometry is in 2D. Steady Brinkman flow, a tertiary current distribution, and the improved modified Donnan description of the deionization process is assumed. Mehr lesen
In an alkaline electrolyzer stack, all cells share the same electrolyte. As a result of all cells being in ionic contact, parasitic shunt currents flow between the cells through the manifolds and the electrolyte channels, on both the inlet and outlet side. This example models a ... Mehr lesen
Mit dieser Serie von acht Tutorial-Modellen und der dazugehörigen Dokumentation können Sie die resistiven, kapazitiven, induktiven und thermischen Eigenschaften eines standardmäßigen dreiadrigen bleiummantelten XLPE-HVAC-Unterseekabels mit verdrillter Magnetarmierung (500 mm2, 220 kV) ...
