Polymer-Hydrogele bestehen aus einem Netzwerk langkettiger Polymere, in das eine große Anzahl von Lösungsmittelmolekülen eingelagert ist. Solche Materialien werden in vielen biomedizinischen Anwendungen eingesetzt, zum Beispiel bei der gezielten Abgabe von Medikamenten, der Züchtung von ... Mehr lesen
The stresses in a pulley connected to an engine that drives another pulley are studied in this model. A parametric analysis is conducted in order to study how the rotational speed affects the stress distribution in the pulley. The power at the pulley shaft remains constant, the moment ... Mehr lesen
During the design of a building, environmental issues have gained considerable influence in the entire project. One of the first concerns is to improve thermal performances. In this process, simulation software are key tools to model thermal losses and performances in the building. The ... Mehr lesen
When radiation occurs across a very narrow gap this is often well-approximated as radiation between infinite parallel plates. This model considers three aluminum plates separated by narrow air gaps. The model compares the classical approach, based on the Surface-to-Surface Radiation ... Mehr lesen
The model demonstrates the basics of the 3-omega method. The coupled electromagnetic heating problem is solved in a solid sample which is heated by a thin copper strip, deposited on the surface of a sample. Analyzing the frequency dependence of the voltage oscillation amplitude, we ... Mehr lesen
Capacitively coupled RF discharges can operate in two distinct regimes depending on the discharge power. In the low power regime, known as the alpha regime, the electric field oscillation is responsible to heat and create electrons. In the high power regime, known as gamma regime, the ... Mehr lesen
The catenary is the geometrical shape that corresponds to the curve followed by an idealized chain or cable supported at both ends and hanging under its own weight. The viscous catenary problem describes the motion of a cylinder of highly viscous fluid, supported at its ends as it flows ... Mehr lesen
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 ... Mehr lesen
This tutorial model presents a study of a double-headed streamer in nitrogen at atmospheric pressure. An initial seed of electrons is placed between two electrodes which apply an initial electric field of 52 kV/cm to the gas. A negative and positive streamer propagate toward the ... Mehr lesen
Das folgende Beispiel demonstriert Techniken zur Modellierung einer Fluid-Struktur-Interaktion mit zwei Fluidphasen in COMSOL Multiphysics. Es veranschaulicht, wie ein schwereres Fluid mithilfe der Methode Arbitrary Lagrangian-Eulerian (ALE) zusammen mit der Anwendung von Two-Phase Flow, ... Mehr lesen
