The Heat Transfer branch (
) included with this module has a number of physics interfaces that can be used to model energy transport. One or more of these can be added; either by themselves or together with other physics interfaces, typically flow physics interfaces.
While the standard COMSOL Multiphysics package includes physics interfaces for simulating heat transfer through conduction and convection, this module provides extra functionality within the standard Heat Transfer interfaces. The CFD Module also includes additional Heat Transfer interfaces such as
The Heat Transfer in Porous Media Interface.
For heat transfer in single-phase flows, the CFD Module provides several turbulent (RANS) versions of the Nonisothermal Flow (
) (located under the
Fluid Flow branch) and
Conjugate Heat Transfer (
) (located under the
Heat Transfer branch) multiphysics interfaces as well as three turbulent (LES) versions of the
Nonisothermal Flow (
) multiphysics interfaces, in addition to the laminar version available with the standard COMSOL Multiphysics
package. The multiphysics interfaces automatically couple the flow and heat equations and they also provide functionality, such as support for turbulent heat transfer, that is not readily available when adding the interfaces separately.
The Heat Transfer in Solids (
)
, Heat Transfer in Fluids (
) (general convection and conduction), and
Electromagnetic Heating>Joule Heating interfaces (
), all belong to the COMSOL Multiphysics base package.
The Heat Transfer in Porous Media interface (
) is an extension of a the generic heat transfer interface that includes modeling heat transfer through convection, conduction and radiation, conjugate heat transfer, and nonisothermal flow. The ability to define material properties, boundary conditions, and more for porous media heat transfer is also activated by selecting the
Heat transfer in porous media check box on any heat transfer interface.
The Nonisothermal Flow (
) and
Conjugate Heat Transfer (
) interfaces solve the Navier-Stokes equations together with an energy balance. They can also solve for heat transfer in solids.
