Heat transfer is the flow of heat due to temperature differences, as well as temperature distribution and changes. Its three applications are:

• Conduction - It is the heat transfer from a hot to a cold object, that are in direct contact with each other. The thermal conductivity of the different objects decides how much heat in which time is being transferred.

• Convection - It occurs when molecules absorb heat and start moving. As you can imagine, these effects are difficult to predict which is why high computing power is needed to obtain reliable results from a simulation.

• Radiation - Electromagnetic waves are the source of heat transfer through radiation. They usually play a role at high temperatures. The amount of heat that is emitted via radiation depends on the surface type of the material. A general rule is that the more surface there is, the higher the radiation is.
