Pitting corrosion is localized corrosion by which local cavities, pits, are formed on a seemingly initially smooth metal surface. A pit may be initiated due to small surface defects, such as inhomogeneities in composition or shape, or from mechanical abuse. How and if the pit grows ... En savoir plus
Chemical engineering students can model a nonideal tubular reactor, including radial and axial variations in temperature and composition, and investigate the impact of different operating conditions with this easy-to-use app. The process described by the Tubular Reactor with ... En savoir plus
An acousto-optic modulator (AOM) is a device which can be used for controlling the power, frequency or spatial direction of a laser beam with an electrical drive signal. It is based on the acousto-optic effect, that is, the modification of the refractive index by the oscillating ... En savoir plus
A model of a thermal microactuator requires the coupled simulation of electric current conduction with heat generation, heat conduction, and structural stresses and strains due to thermal expansion. The purpose of this model is to demonstrate how to access the cluster computing ... En savoir plus
The thermal effects of a laser beam incident on a Semiconductor Saturable Absorber Mirror (SESAM) are simulated under a range of incident beam powers. This is done in two steps. The first study simulates the multiphysics combination of the saturated absorption of the beam on a SESAM, ... En savoir plus
Thermoelastic damping, which arises when you subject a material to cyclic stress, is an important factor when designing MEMS resonators. The stress brings about deformation, where materials heat under compressive stress and cool under tensile stress. Thus, due to the resulting heat flux, ... En savoir plus
This model shows how to model a simple Shockley diode— a four-layer PNPN semiconductor device. The Shockley diode is also named as thyristor. In this model, the Analytic Doping Model node is utilized to define the doping profiles for each domain. A time-dependent study is employed to ... En savoir plus
This tutorial demonstrates how to model a gyroscope based on the birdbath resonator gyroscope (BRG) design. The BRG is a type of Coriolis vibratory gyroscope (CVG) invented at the University of Michigan as a navigation-grade gyroscope in the mm-scale. This tutorial shows how the ... En savoir plus
This tutorial digs deeper into the investigation of rate capability in a battery and shows how the Lithium-Ion Battery interface is an excellent modeling tool for doing this. The rate capability is studied in terms of polarization (voltage loss) or the internal resistance causing this ... En savoir plus
Crystallization is an important separation process in the chemical industry. It is used for the production of pharmaceuticals and industrial chemicals. It can also be used in resource recovery as a way of separating valuable materials from waste. This model solves a discretized ... En savoir plus
