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
This example treats the modeling of sub-surface flow where free convection in porous media is analyzed. The results are compared with published literature in the field. The model couples the momentum balance to an energy balance through an equation, dependent on temperature, being ... En savoir plus
A Lorenz attractor can be described by a system of ordinary differential equations: the Lorenz system. In the early 1960s, Lorenz discovered the chaotic behavior of this system for certain parameter values and initial conditions. The solution, when plotted as a phase space, resembles the ...

A Fresnel rhomb is a prism that uses total internal reflection to manipulate the polarization of light. In this example, light in the prism is internally reflected at an angle of incidence that induces a 45-degree phase delay between s- and p-polarized radiation. By subjecting the light ...

A steel billet is quenched in oil from its austenitic state. A 2D axisymmetric model is used to simulate the coupled problem of austenite decomposition, heat transfer, and solid mechanics. During the quenching process, the austenite decomposes into a combination of ferrite, pearlite, ... En savoir plus
Power lines are commonly used as a means of transmitting electrical power across large distances. In this tutorial, towers transmitting high voltage three-phase AC power are modeled, and the resulting electric field is computed. The towers have two shielding lines. The model also ... En savoir plus
In this example, the brittle fracture of a holed plate with a notch is modeled using a phase-field damage model. The geometry of the plate is set up so that a mixed-mode fracture is induced, with dimensions and material properties taken from experimental data. The example shows how to ... En savoir plus
This model is a benchmark for three-phase flow commonly used in food processing, pharmaceutical industry, and chemical processing. The results are validated against data reported in the literature. A gas bubble rises through two layers of liquid, a lighter liquid resting on top of a ... En savoir plus
A Gaussian beam is incident on a 45-degree thin-film stack embedded in glass material prisms. The thin-film stack is designed from alternating high and low refractive index materials. The wave will be refracted at the Brewster angle at each internal interface. Thus, mainly p-polarized ... En savoir plus
This is the transient model of a single phase E-core transformer using a homogenized approach for the multi-turn primary and secondary coils. The model includes the effect of magnetic saturation (B–H curve) in the core and shows how to connect the transformer model to the external ... En savoir plus
