This verification model of nonisothermal turbulent flow over a flat plate compares the heat transfer coefficient obtained from simulation with theoretical values based on Nusselt number correlation functions that can be found in the literature. Mehr lesen
Thermal management has become a critical aspect of today’s electronic systems, which often include many high-performance circuits that dissipate large amounts of heat. Many of these components require efficient cooling to prevent overheating. Some of these components, such as processors, ... Mehr lesen
Ein Benchmark-Modell des Rainflow-Zählalgorithmus vergleicht die Ergebnisse zwischen dem ASTM- und dem COMSOL-Ermüdungsmodul unter Verwendung eines flachen Zugprüfkörpers. Es wird eine Erweiterung für die Berechnung der kumulativen Schädigung nach dem Palmgren-Miner-Modell vorgenommen ... Mehr lesen
This model exemplifies the basic principles of crevice corrosion and how a time-dependent study can be used to simulate the electrode deformation. The model is in 2D and the polarization data for the corrosion reaction is taken from a paper by Absulsalam and others. The model and the ... Mehr lesen
Tilted pad thrust bearings are used in rotating machineries with high thrust loading. The thrust load is transferred from a sliding part to a stationary part through hydrodynamic oil films. The tilted pad thrust bearing consists of a series of flat surfaces sliding over stationary tilted ... Mehr lesen
An ellipse with sound-hard walls has the interesting property that an acoustic signal emanating from one of the foci refocuses at the other focal point b/c seconds later, where b (in meters) is the major axis length and c (m/s) is the speed of sound. This model involves a Gaussian ... Mehr lesen
This introduction model creates a simple model of the magnetostatics problem with a wire of infinite length carrying current, which is commonly found in textbooks. Since there is an analytical solution to this problem, the model can be used to compare theory with numerical results from ... Mehr lesen
This tutorial studies the propagation of sound in the presence of a porous absorber in the time domain. It demonstrates how to model a porous absorber using the local and extended reacting approximations and compares the two approaches for absorbers of various thickness. The dissipative ... Mehr lesen
This is a model of a MEMS microphone solved in the frequency domain including the DC prestress effects. The model is set up using the Electromechanics multiphysics interface, Thermoviscous Acoustics, and Pressure Acoustics. The microphone consists of a perforated plate and a prestressed ... Mehr lesen
This model simulates the propagation of two frequency bands in a photonic crystal with three ports. The crystal is initially symmetric, so that the two frequency bands are directly equally to either output port. The model optimizes the position of the pillars in order to make the two ... Mehr lesen
