Reflective mufflers are best suited for the low-frequency range where only plane waves can propagate in the system, while dissipative mufflers with fibers are efficient in the mid- to high-frequency range. Dissipative mufflers based on flow losses, on the other hand, also work at low ... En savoir plus
Rechargeable lithium-air batteries have recently attracted great interest mainly due to their high energy density. The theoretical value is about 11400 Wh/kg which is around 10 times greater than the lithium-ion batteries. In this tutorial, discharge of a lithium-air battery is ... En savoir plus
This model uses the Optimization interface to solve the inverse problem for determining the spatially variable hydraulic conductivity on a discretized quadratic grid from a number of aquifer pump tests. Because the number of observations is smaller than the number of unknown parameters, ... En savoir plus
This model investigates the National Institute of Standards and Technology (NIST) Gaseous Electronics Conference (GEC) reference cell in two dimensions using the Plasma, Time Periodic interface. A 2D example helps in understanding the physics without excessive CPU time. The cell is ... En savoir plus
Magnetotellurics is a method for estimating the resistivity profile of the Earth's subsurface using the natural electromagnetic source provided by the ionosphere. This model was defined by Zhdanov et al. in a study published in 1997. In this article, various scientific groups compared ... En savoir plus
A modern high-power industrial fiber laser system can deliver up to 3kW of single-mode laser radiation on to surfaces to be cut, drilled, welded or marked. Even using highly transmissive materials, the optical component used to focus the laser beam onto target surfaces can be affected ... En savoir plus
This example simulates particles in a range of sizes that move through different levels of a cascade impactor. A cascade impactor is an inertial particle separation device consisting of multiple levels separated by collecting plates and nozzles. Particle-laden air enters from the top ... En savoir plus
Fluid dampers are used in military devices for shock isolation and in civil structures for suppressing earthquake-induced shaking and wind-induced vibrations, among many other applications. Fluid dampers work by dissipating the mechanical energy into heat. This model shows the phenomenon ... En savoir plus
At the macroscopic level, systems usually mix fluids using mechanical actuators or turbulent 3D flow. At the microscale level, however, neither of these approaches is practical or even possible. This model demonstrates the mixing of fluids using laminar-layered flow in a MEMS mixer. This ... En savoir plus
This example is an extension of a model used to study the vibration and noise in a 5-speed synchromesh gearbox in a manual transmission vehicle. In this version of the model, a detailed representation of a roller bearing is used instead of hinge joints with elastic stiffness. First, the ... En savoir plus
