This example demonstrates how to model phase transition by a moving boundary interface according to the Stefan problem. A square cavity containing both solid and liquid tin is submitted to a temperature difference between left and right boundaries. Fluid and solid parts are solved in ... 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
This tutorial model shows how a plate-fin heat exchanger made of aluminum is used to cool down hot oil with colder air. In order to maximize heat transfer, the heat exchanger is made of a porous aluminum matrix in which the hot oil flows. Heat is conducted through aluminum fins in ... 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
Thermal management of a battery pack is simulated considering two scenarios, air (natural convection) and phase change material (PCM) in the gap between the batteries. The PCM considered is a composite material of paraffin wax and graphite additive. Graphite is typically added for ... En savoir plus
This 2D stationary model computes heat and moisture transport in a wall composed of different hygroscopic materials. A comparison with the Glaser method is given for the temperature and relative humidity solutions. The effect of the use of a vapor barrier is also investigated. 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
This example models the transient heating, and final temperature, of a disc brake of a car in brake-and-release sequence. It is important to model the transient heating and the following convective cooling to determine the minimum interval between a series of similar brake engagements. ... En savoir plus
This model treats the free convection and heat transfer of a glass of cold water heated to room temperature. Initially, the glass and the water are at 5 °C and are then put on a table in a room at 25 °C. The nonisothermal flow is coupled to heat transfer using the Heat Transfer module. En savoir plus
This example demonstrates how to model a phase change and predict its impact on a heat transfer analysis. When a material changes phase, for instance from solid to liquid, energy is added to the solid. Instead of creating a temperature rise, the energy alters the material’s molecular ... En savoir plus
