Radial and Linear Heat Conduction

Heat conduction is one of the three basic forms of heat transfer. Kinetic energy is transferred between neighbouring atoms or molecules. The heat transport is material-bound. 

The experimental unit includes a linear and a radial experimental setup, each equipped with a heating and cooling element. The measuring unit is used to determine basic laws and characteristic variables of heat conduction in solid bodies by way of experiment. This type of heat transfer is an irreversible process and transports heat from the higher energy level, ie If the heat transport is maintained by the supply of heat, this is called steady heat conduction. The most common application of heat conduction in engineering is in heat exchangers. With different heat transfer properties can be installed in the experimental setup for linear heat conduction. The experimental unit includes with a display and control unit. Sensors record the temperatures at all relevant points.
