This example shows how to set up multiple sandwiched thin layers with different thermal conductivities in two different ways. First, the composite is modeled as a 3D object. In the second approach, the thin domains are modeled with thermal resistors in the Lumped Thermal System ... En savoir plus
This tutorial model demonstrates the use of the Moisture Flow coupling node to account for the Stefan flow in moist air, over an evaporation surface. The effects on the velocity field and vapor concentration are presented with different ambient temperature conditions. En savoir plus
Because the atmosphere is nearly transparent to wavelengths in the range 8 to 13 µm (atmospheric window) for a clear sky, it is possible to cool down a surface even during a sunny day. This model compares the temperature distribution on a concrete block exposed to ambient and solar ... En savoir plus
This example shows how to set up a model of furrow irrigation in a nonuniform soil column. It employs the Unsaturated Dual Permeability feature, which links two Richards' Equations through a fluid transfer function. This scenario can be regarded as a benchmark problem for dual ... En savoir plus
A lab-on-a-chip platform can be realized on a rotating disc by designing channels and other features to use the Coriolis or centrifugal forces to manipulate the flow. These forces are controlled by changing the angular velocity of the disc, so the platform is programmed by using a ... En savoir plus
This example describes how to simulate the flow of a thin film of fluid in the gap between two rectangular plates, one of them with a porous facing, when the fluid is squeezed as a consequence of the relative motion between the plates. The model accounts for the ingress and egress of ... En savoir plus
Thermoelectric coolers are widely used for electronics cooling in various application areas, ranging from consumer products to spacecraft design. The thermoelectric modules are a common application of thermoelectricity in cooling engineering. They consist of several thermoelectric legs ... En savoir plus
This model shows how to compute an array of borehole heat exchangers (BHEs) for shallow geothermal energy production. The BHEs are simplified as line heat sinks with a uniform heat extraction rate. The array is embedded into a layered subsurface model with groundwater flow in one of the ... En savoir plus
A 3D model of an acoustic trap in a glass capillary with a bias flow through the capillary. The acoustics is actuated by an oscillating electric potential across a piezoelectric transducer, inducing mechanical vibrations in the solid, and an acoustic pressure field in the fluid. The heat ... En savoir plus
This model demonstrates how to define Earth properties that are spatially varying on the planet. A satellite in orbit experiences solar, albedo, and planetary infrared (IR) loads, where albedo and planetary IR can vary with latitude and longitude. In this example, these inputs are read ...
