Fluid dampers are used in military devices for shock isolation and in civil structures for suppressing earthquake-induced shaking and wind-induced vibrations, among many other applications. Fluid dampers work by dissipating the mechanical...
This example simulates the thermodynamical evolution of moist air in an electronic box with the aim of detecting whether condensation occurs when the external environment properties change. The model imports measured data for the air...
This example shows how to model forced turbulent convection cooling with COMSOL Multiphysics. Two different approaches are demonstrated. The first one uses the K-epsilon Turbulent Flow interface together with the Heat Transfer...
This model how to build and solve a conductive heat transfer problem using the Heat Transfer interface. The model, taken from a NAFEMS benchmark collection, shows an axisymmetric steady-state thermal analysis. As opposed to the NAFEMS...
In this example, we study the transport by convection and conduction. Such a system may be found in a heat exchanger or in heating of endothermic reactors. The fluid flow enters the unit cell from below and the fluid is heated as it...
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.
This model uses the discrete-ordinates method (DOM) to analyze the radiative heat transfer in a utility boiler with internal obstacles. DOM is one of the most useful radiation models for prediction of radiative heat fluxes on the furnace...
Furnace reactors are used in the fabrication of semiconductors to grow layers on wafers. These can also be used for epitaxial growth, which is a key technology for fabrication of electrical devices. A silicon carbide growth takes place...
This model simulates a static analysis of heat conduction in a thin conductive shell. This is a benchmark model where the result is compared with a NAFEMS benchmark solution.
This model illustrates how to implement a multiphysics contact. It models the thermal and electrical behavior of two contacting parts of a switch. The electrical current and the heat flow from one part to the other only through the...
