This tutorial shows how to use the Surface-to-Surface Radiation interface to simulate radiative heat transfer with radiation between diffuse emitters and diffuse-and-specular reflectors. This model is separated in two parts. The first part focuses on a validation test for the radiative ... En savoir plus
This example solves the heat transfer in an isothermal box aimed at transporting refrigerated articles such as medical materials for 24 hours. In this case, the box has to keep the contents cold for a long period of time while respecting storage temperature restrictions between 2°C and 8 ... 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 problem follows a typical preliminary board-level thermal analysis. First perform a simulation of the board with some Integrated Circuits (ICs). Then, add a disk-stack heat sink to observe cooling effects. Finally, explore adding a copper layer to the bottom of the board in order to ... En savoir plus
In the semiconductor industry, rapid thermal annealing (RTA) is a semiconductor process step used for the activation of dopants and the interfacial reaction of metal contacts. In principle, the operation involves rapid heating of a wafer from ambient to approximately 1000–1500 K. As soon ... En savoir plus
This verification model of nonisothermal laminar flow through a circular tube compares the heat transfer coefficient obtained from simulation with theoretical values based on Nusselt number correlation functions that can be found in the literature. En savoir plus
When a temperature gradient in a gas exists, suspended particles will tend to move from regions of high temperature to low. The force which produces this effect is called the thermophoretic force. Gas molecules colliding with a particle from the hot side have a higher velocity than the ... En savoir plus
The response of a millimeter wave with frequencies of 35 GHz and 95 GHz is known to be very sensitive to water content. This model utilizes a low-power 35 GHz Ka-band millimeter wave and its reflectivity to moisture for noninvasive cancer diagnosis. Since skin tumors contain more ... En savoir plus
The model is defined as a benchmark case in norm 15026:2007 annex A. The purpose of the model is to calculate the temperature and moisture profiles at different times after a change in the external conditions (temperature and relative humidity) inside a wall material (kind of concrete). ...
