Heat Conduction in a Finite Slab

This simple example covers the heating of a finite slab and how the temperature varies with time. We will set up the problem in COMSOL Multiphysics after which we compare the solution to the analytical solution. Read More

Radiative Cooling of a Glass Plate

When producing glass, the glass melt is cooled down through radiation to form the final shape, subjecting it to stresses. Numerical treatment of radiative heat transfer, using the Radiative Transfer Equation (RTE), helps to optimize this process. COMSOL Multiphysics provides three ... Read More

Out-of-Plane Heat Transfer for a Thin Plate

This example models heat transfer in a thin rectangular metal plate. Because the plate’s thickness is only 1/100 of its length and width, you can simulate the process using a 2D approximation. The plate has a fixed temperature at one end and is isolated at the other. A surrounding liquid ... Read More

Inline Induction Heater

Ferritic stainless steels have become more and more popular in the food industry because of their relatively low and stable price and due to the absence of nickel in their components. Their resistance to corrosion can be improved by adding chromium or molybdenum, and their magnetic ... Read More

Composite Thermal Barrier

This example shows how to set up multiple sandwiched thin layers with different thermal conductivities in two different ways. First, the composite is modeled as a 3D object. In the second approach the Thin thermally resistive layer boundary condition is used to avoid resolving the thin ... Read More

Radiative Heat Transfer in Finite Cylindrical Media — P1 Method

This model uses the Discrete-Ordinates method (DOM) to solve a 3D radiative transfer problem in an emitting, absorbing, and linear-anisotropic scattering finite cylindrical medium. Using the S6 quadrature of DOM leads to faster and more accurate results, which are needed in combined ... Read More

Disk-Stack Heat Sink

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 ... Read More

Isothermal Box

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 not only has to keep the content cold in a long period of time, but also has to respect a storage temperature restriction. ... Read More

Turbulent Flow Through a Shell-and-Tube Heat Exchanger Cross Section

This model studies a part of a shell-and-tube heat exchanger where hot water enters from above. The cooling medium flows through the tubes that, in this model, impose a constant temperature at the walls. Furthermore, the tubes are assumed to be made of stainless steel and the heat flux ...

Dynamic Wall Heat Exchanger

The heat exchanger in this tutorial model contains a dynamic wall with an oscillating wave shape. The deformation induces mixing in the fluid and reduces the formation of thermal boundary layers. Hence, it increases heat transfer between the walls and the fluid. In addition, the wave ... Read More
