It may represent a safety hazard, or an opportunity depending on the process. Definition of Thomson effect. : a redistribution of temperature differences along an otherwise homogeneous strip of metal due to an electric current passing through it. — called also Kelvin effect. — see thomson electromotive force.

The Joule-Thomson Effect describes the change in temperature of a gas as it experiences a rapid change in pressure from passing through a valve, orifice or nozzle.

Chemistry 030.307 Fall 2008. Experiment 1: Joule-Thomson Effect. The familiar cooling of a compressed gas upon expansion is a result of the non-ideal behavior

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.

Finally, we observe the quantum Joule-Thomson effect, namely isoenthalpic cooling of an (essentially) ideal gas. In our experiments this cooling occurs

This effect is based on a current-conducting material as a base, which is heated or cooled by 2017-10-30 physics the phenomenon in which a temperature gradient along a metallic (or semiconductor) wire or strip causes an electric potential gradient to form along its length Word Origin for Thomson effect named after Sir William Thomson, Lord Kelvin The ideal equation is obtained when the Thomson coefficient is assumed to be 0. The exact solutions derived for a commercial thermoelectric cooler module provide the temperature distributions including the Thomson effect. The compatibility factor is a thermodynamic property essential for designing an efficient segmented thermoelectric device. Discovered by W. Thomson (Lord Kelvin) in 1851, the Thomson effect is a manifestation of magnetoresistance, which is a galvanomagnetic phenomenon.

The compatibility factor is a thermodynamic property essential for designing an efficient segmented thermoelectric device. 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.

The Joule-Thomson effect, also known as the Joule-Kelvin effect, refers to the change which takes place in fluid’s temperature as it flows from a region of higher pressure to lower pressure.

Refer to the image shown above that helps understand the effect of Joule Thomson law quickly. To illustrate this, a gas packet is placed opposite to the flow of direction in a Joule Thomson valve.
