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 ...

The following example solves a pure conduction and a free-convection problem in which a vacuum flask holding hot coffee dissipates thermal energy. The main interest is to calculate the flask's cooling power; that is, how much heat it loses per unit time. This tutorial model treats the ... En savoir plus
A capacitive pressure sensor is simulated. This model shows how to simulate the response of the pressure sensor to an applied pressure, and also how to analyze the effects of packing induced stresses on the sensor performance. En savoir plus
All integrated circuits (ICs) — especially high-speed devices — produce heat. In today’s dense electronic system layouts, heat sources are many times placed close to heat-sensitive ICs. Designers of printed circuit boards often need to consider the relative placement of heat ... En savoir plus
Double-pipe heat exchangers, with their typical U-turn shape, are one of the simplest and cheapest type of heat exchangers used in the chemical process industry. This example studies the cooling of hot oil (130°C) by a cool oil (60°C) entering in counter-current. As the oils flow ... En savoir plus
One method for removing cancerous tumors from healthy tissue is to heat the malignant tissue to a critical temperature that kills the cancer cells. This example accomplishes the localized heating by inserting a four-armed electric probe through which an electric current runs. Equations ... En savoir plus
This example studies heat transfer in a composite two-dimensional structure. Four materials with distinct thermal conductivities k compose the structure. The top and bottom boundaries are facing environments respectively at 0°C and 20°C. The temperature distribution and the heat flux ... En savoir plus
This model studies the heat conduction in a building structure separating two floors from the external environment. Four materials with distinct thermal conductivities k compose the structure. The exterior and interior boundaries are facing environments respectively at 0°C and 20°C. The ... En savoir plus
This model solves the fluid flow and heat transfer in a micro heat exchanger made of stainless steel. These types of heat exchangers are found in lab-on-chip devices in biotechnology and micro reactors, for example for micro fuel cells. The model takes heat transferred through both ... En savoir plus
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
