Hoppa till Interface heat transfer – The heat transfer at an interface is considered a transient heat flow. To analyze this problem, the Biot number is . Heat_conductionCachadLiknandeÖversätt den här sidanHeat conduction (or thermal conduction) is the movement of heat from one solid to another one that has different temperature when they are touching each other.

The transfer of heat is normally from a high temperature object to a lower temperature object. Heat transfer changes the internal energy of both systems involved . Heat transfer by conduction can be used to model heat loss through a wall. For a barrier of constant thickness, the rate of heat loss is given by: .

Heat transfer takes place as conduction in a soilid if there is a temperature gradient. Heat can only be transferred through three means: conduction, convection and radiation. Of these, conduction is perhaps the most common, . All matter is made up of molecules and atoms.

These atoms are always in different types of motion (translation, rotational, vibrational). Heat can be transferred from place to place by conduction, convection and radiation. Dark matt surfaces are better at absorbing heat energy than light shiny . Heat conduction, also known as thermal conduction, is the process where heat is transferred within a body due to the collision of neighboring particles.
