5.1 Thermodynamics of Thomson Effect The thermoelectric effect consists of three effects: the Seebeck effect, the Peltier effect, and the Thomson effect. Some gases, such as hydrogen and helium, will experience a warming effect upon expansion under conditions near room temperature and pressure. The direction of temperature change can be determined by measuring the Joule-Thomson coefficient, μ J T. This coefficient has the definition (4.5.1) μ J T ≡ (∂ T ∂ p) H Thomson effect can be explained on the basis of free electron theory of metals. The density of free electrons in a metal depends upon temperature.

Phase-field modeling of diffusion controlled phase

Beside the Seebeck and Peltier effect, Thomson (later Lord Kelvin) observed the third thermoelectric effect.Assuming a homogeneous conductor with a temperature gradient applied, carriers traversing the temperature gradient gain or release energy depending on their relative direction to the temperature gradient. The Joule-Thomson effect (also known as Joule-Thomson Expansion and the Joule-Kelvin effect) is the change in temperature of a fluid as it flows from a region of high pressure to a region of low pressure. Joule Thomson Effect Definition. When a real gas is subjected to adiabatic expansion process, where no heat is exchanged with the surroundings, it looses its temperature. .

Thomson suggested that when a current flows through unequally heated conductors, heat energy is absorbed or evolved throughout the body of the metal. Fig: Thomson effect.

From experience it is known (since Joule and Thomson carried out their experiments in the ninetieth century [50]) that temperature of most gases decreases when pressure is lowered in a flowing gas by throttling. This effect is called the Joule–Thomson effect and is easily experienced while experimenting with carbon dioxide [30]. Discovered by W. Thomson (Lord Kelvin) in 1851, the Thomson effect is a manifestation of magnetoresistance, which is a galvanomagnetic phenomenon. In Thomson effect, we deal with only metallic rod and not with a thermocouple as in Peltier effect and Seebeck effect.
