Physics. the tendency of unevenly heated segments of a strip of a conductor to increase or decrease in temperature … •Thomson heat is proportional to both the electric current and the temperature gradient. TH I TO Note that Thomson effect is different from Peltier effect or Joule heating. Using the plots of the DOS and the hole energy spectra across a thermoelectric material show that the Thomson effect results in cooling of a p type TE material used as a Thomson effect is something which states that the generation of reversible heat is possible when the passage of electrical current is sent via a conducting material under a certain temperature gradient. The thermoelectric cooling devices are dependent on the Peltier effect. Each effect generated from the Peltier experiment is meant to convert LEP 3.2.06 Joule-Thomson effect PHYWE series of publications • Laboratory Experiments • Physics • PHYWE SYSTEME GMBH • 37070 Göttingen, Germany 23206 1 Related topics Real gas; intrinsic energy; Gay-Lussac theory; throttling; Van der Waals equation; Van der Waals force; inverse Joule-Thomson effect; inversion temperature.

For the case of the Joule-Thomson effect, both cooling and heating are produced. It depends on the Inversion temperature of the gas. Thomson suggested that when a current flows through unequally heated conductors, heat energy is absorbed or evolved throughout the body of the metal. Positive Thomson effect: Consider a copper bar Originally proposed by William Thomson (also known as Lord Kelvin), the Thomson effect links together the Peltier coefficient Π (the heat absorbed/evolved per unit charge) and the Seebeck coefficient S (the voltage generated per unit temperature difference) at any temperature T 0, using Π = S T 0 and the Thomson coefficient 𝜏 = S ⋅ d S ∕ d T [ 3 ]. The Thomson effect describes the heating or cooling of a current-carrying material subject to a temperature gradient and was discovered by William Thomson (Lord Kelvin) in 1851 (11).

Fig: Thomson effect. Consider a copper bar AB heated in the middle at the point C and current flowing as shown in Fig: a. This is called as "Thomson Effect". The thermoelectric effect is the direct conversion of heat differentials to electric voltage and vice versa. The good thermoelectric materials should possess large seebeck coefficients, high electrical conductivity and low thermal conductivity. 2017-10-30 · Thermoelectric effects, such as Seebeck effect, Peltier effect and Thomson effect, result from the interference of electrical current and heat flow in various semiconductor materials , and its interaction allows to use thermoelectric effects to generate electricity from a temperature differential; conversely, cooling phenomena occurs when a voltage is applied across a thermoelectric material. The phenomenon of producing lowering of temperature when a gas is made to expand adiabatically from a region of high pressure into a region of low pressure, is known as Joule-Thomson Effect or Joule-Kelvin Effect.
