Question

Examples of heat conduction with internal heat generation

Answer 1

The temperature of a resistance wire rises rapidly when electriccurrent passes through it as a result of the electrical energy being convertedto heat at a rate of I2R, where I is the current and R is the electricalresistance of the wire The safe and effective removal of this heataway from the sites of heat generation (the electronic circuits) is the subjectofelectronics cooling, which is one of the modern application areas of heat transfers

Answer 2

Answer:

The natural disintegration of radioactive elements in nuclear waste or other radioactive material is an example of heat conduction with internal heat generation.

Explanation:

A medium thru which heat is carried out may contain the conversion of mechanical, electrical, nuclear, or chemical power into heat (or thermal power). In heat conduction analysis, such conversion techniques are characterized as heat generation.

For example, the temperature of a resistance wire rises hastily whilst electric current passes thru it because of the electric power being converted to heat at a rate of I²R, in which I is the current and R is the electrical resistance of the wire. The secure and powerful elimination of this heat away from the sites of heat generation (the electronic circuits) is the subject of electronics cooling, that is one of the current software regions of heat transfer.

Likewise, a huge quantity of heat is generated withinside the gasoline factors of nuclear reactors because of nuclear fission that serves as the heat supply for the nuclear power plants.
