In this model, we show how to model Seebeck effect which works as a thermoelectric generator. Seebeck effect is a phenomena where the difference in temperature of a material leads to a potential difference. The potential drawn in this model was compared with the paper by Jaegle (Example ...

This example considers the turbulent flow of an oil-water suspension through an orifice. The oil droplets are broken up into smaller droplets by the turbulent stresses as the suspension passes through the orifice. The aim of this model is to track the distribution of droplet sizes. The ... En savoir plus
In friction stir welding, a rotating tool moves along the weld joint and melts the aluminum through the generation of friction heat. The tool’s rotation stirs the melted aluminum such that the two plates are joined. In this model, two aluminum plates are joined by generating friction ... En savoir plus
This model describes the three heat transfer modes: conduction, convection, and radiation, combined with nonisothermal flow in a realistic geometry representing a light bulb and the surrounding air. The LED chips dissipate heat. The model computes the equilibrium temperature induced by ... En savoir plus
The drive for miniaturizing electronic devices has resulted in today’s extensive use of surface-mount electronic components. An important aspect in electronics design and the choice of materials is a product’s durability and lifetime. For surface-mount resistors and other components ... En savoir plus
This example studies the stationary state of free convection in a cavity filled with air and bounded by two vertical plates. To generate the buoyancy flow, the plates are heated at different temperatures, set in a range to keep the flow laminar. En savoir plus
This example illustrates how to model the transport of different contaminants through a ceramic water filter candle with an activated carbon core. These types of water filters can be found in table top gravity filters, as well as attached to the faucet or as part of a larger reverse ... En savoir plus
This model shows how to compute the thickness of a thermally evaporated gold film. The thickness of the deposited film is computed both on the walls of the chamber and on the sample. En savoir plus
A thermoelectric leg is a fundamental component of a thermoelectric cooler (or heater). For example, a thermocouple is a thermoelectric module typically made of two thermoelectric legs: one made of p-type and of one n-type semiconductor material which are connected in series electrically ...

When cooking food, such as a patty, in convection ovens there is a trade off in the heating method. If the patty is heated at a low oven temperature the cooking is slow and the patty dries out, resulting in a poor taste. If the patty is heated rapidly at a high temperature, it is ... En savoir plus
