This example demonstrates how to optimize the thickness of a microelectromechanical systems (MEMS) mirror coating material for maximum reflectivity. To reduce the simulation time, a Layered Impedance Boundary Condition is used to model the thin coating material on top of the metallic ... Mehr lesen
Dieses nicht-konventionelle Modell der Strömung in porösen Medien nutzt die schleichende (Stokes-) Strömung in den Zwischenräumen eines porösen Mediums. Das Modell stammt aus den von Arturo Keller, Maria Auset und Sanya Sirivithayapakorn von der University of California, Santa Barbara, ... Mehr lesen
A fuel cell stack operates at temperatures just below 100 °C, which means that it has to be heated at start-up. The fuel cell stack consists of unit cell of anode, membrane, and cathode connected in series through bipolar plates. This study presents a model that couples the thermal and ... Mehr lesen
In the surface acoustic waves industry different crystal cuts of piezoelectric materials are used, e.g. 128ᵒ YX LiNbO3, AT&ST quartz, 42ᵒ YX LiTaO3, etc. Direct data isn’t available for all cuts. The standard approach is to use the so-called Euler angle rotation. COMSOL supports it ... Mehr lesen
This example showcases a helical planetary gear train composed of a sun gear, ring gear, carrier, and five planet gears. Three cases are analyzed by in turn fixing the ring gear, sun gear, and carrier. For each configuration, a transient multibody analysis is performed to determine the ... Mehr lesen
This model simulates a GaN based light emitting diode. The emission intensity, spectrum, and quantum efficiency are calculated as a function of the driving current. Direct radiative recombination across the band gap is modeled, as well as non-radiative Auger and trap-assisted ... Mehr lesen
Carbon dioxide in aqueous solution is highly corrosive and can cause significant damage to steel designs. Such conditions arise in pipes used in a variety of applications, especially within the petrochemical industry. In this tutorial example, turbulent flows consisting of carbon ... Mehr lesen
This model computes the trajectory of an ion in a uniform magnetic field using the Newtonian, Lagrangian and Hamiltonian formulations available in the Mathematical Particle Tracing interface. 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
This model illustrates how to compute the torque of a three-phase squirrel-cage induction motor at various speeds. In the example the torque is computed by averaging the results from simulations performed on 2D cross sections at several locations along the induction motor. The 3D ... Mehr lesen
