Anisotropic Heat Transfer through Woven Carbon Fibers

This model and presentation shows how to model anisotropic properties of fibers in a heat transfer simulation. Because the fibers orientation is not easy to define explicitly, the curvilinear coordinate interface is used to define the fiber orientation. The fibers have high thermal ... Per saperne di più

Natural Convection Cooling of a Vacuum Flask

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 ... Per saperne di più

Microwave Heating of a Cancer Tumor

Electromagnetic heating is ideally suited for modeling in COMSOL Multiphysics. This model shows the area of hyperthermic oncology but the modeling issues and techniques are generally applicable to any problem involving electromagnetic heating. The purpose of this model is to compute the ... Per saperne di più

Heat Generation in a Disc Brake

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. ... Per saperne di più

Double-Pipe Heat Exchanger

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 ... Per saperne di più

Continuous Casting

This example models the casting process of a metal rod from liquid to solid state using the Non-Isothermal Flow multiphysics interface, which combines heat transfer and fluid flow. The model describes the fluid and solid flow and heat transport, including the phase transfer from melt to ... Per saperne di più

Heat and Moisture Transport in a Semi-Infinite Wall

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). ...

Forced Air Cooling with Heat Sink

Heat sinks are usually benchmarked with respect to their ability to dissipate heat for a given fan curve. One possible way to carry out this type of experiment is to place the heat sink in a rectangular channel with insulated walls. The temperature and pressure at the channel’s inlet ...

Thermal Stress Analysis of a Turbine Stator Blade

The conditions within gas turbines are extreme. The pressure can be as high as 40 bar, and the temperature more than 1000 K. Any new component must therefore be carefully designed to be able to withstand thermal stresses, vibrations and loads asserted by the fluid rushing through the ... Per saperne di più

Forced Convection Cooling of an Enclosure with Fan and Grille

This study simulates the thermal behavior of a computer Power Supply Unit (PSU). Most of such electronic enclosures include cooling devices to avoid electronic components to be damaged by excessively high temperatures. In this model, an extracting fan and a perforated grille cause an air ... Per saperne di più
