The Czochralski (CZ) method is one of the most important methods for the preparation of monocrystalline silicon. The shape of the crystal, especially the diameter, is controlled by carefully adjusting the heating power, the pulling rate, and the rotation rate of the crystal. This model ... Mehr lesen
In this model the high speed turbulent gas flow in a converging and diverging nozzle is modeled using the High Mach Number Flow interface. The diffuser is transonic in the sense that the flow at the inlet is subsonic, but due to the contraction and the low outlet pressure, the flow ... Mehr lesen
The topology optimized Tesla microvalve is used as an inspiration for an initial geometry. Second order Bernstein polynomials are used to perturb the shape of the geometry. The resulting design is remeshed in the deformed configuration and the performance is investigated for a range of ... Mehr lesen
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 ... Mehr lesen
When simulating surface-to-surface radiation, we rely on the view factors between elements of diffuse surfaces that emit and receive radiation. To compute surface-to-surface radiation in a given geometry, operators are created by the heat interface and can be used to evaluate view ... Mehr lesen
This tutorial presents the averaging models available within the Heat Transfer in Porous Media interface, used to compute the effective thermal conductivity, when the local thermal equilibrium assumption is made. The models are compared for porosities ranging from 0 to 1, and for a ... Mehr lesen
This model demonstrates how to couple the Radiative Beam in Absorbing Media interface to the Radiation in Absorbing-Scattering Media interface. To learn more about this model, see our accompanying blog post “Modeling Absorption and Scattering of Collimated Light”. Mehr lesen
Seawater intrusion is a critical issue in coastal regions, where it endangers both freshwater supplies and the overall quality of groundwater. This example showcases seawater intrusion in a coastal aquifer where a pumping well is located at some distance from the shoreline. The model ... Mehr lesen
Fluids that move through pore spaces in an aquifer or reservoir can shield the porous medium from stress because they bear part of the load from, for instance, overlying rocks, sediments, fluids, and buildings. Withdrawing fluids from the pore space increases the stress the solids bear, ... Mehr lesen
This application presents an example of pressure driven flow and electrophoresis in a 3D micro channel system. Researchers often use a device similar to the one in this model as an electrokinetic sample injector in biochips to obtain well-defined sample volumes of dissociated acids and ... Mehr lesen
