Remains flexible at Joule – Thomson Effect • Remains flexible at Arctic Storage • Resists shock from arctic storage to subsea deployment 

The density of free electrons in a metal depends upon temperature. The free electron in the hotter region have more energies than that of the free electrons in the colder region. From HandWiki In thermodynamics, the Joule–Thomson effect (also known as the Joule–Kelvin effect or Kelvin–Joule effect) describes the temperature change of a real gas or liquid (as differentiated from an ideal gas) when it is forced through a valve or porous plug while keeping it insulated so that no heat is exchanged with the environment. The Joule-Thomson (JT) effect is a thermodynamic process that occurs when a fluid expands from high pressure to low pressure at constant enthalpy (an isenthalpic process). Such a process can be approximated in the real world by expanding a fluid from high pressure to low pressure across a valve. Numerical simulations on the Thomson effect using CFD software ANSYS for miniature thermoelectric coolers revealed that the cooling power can be improved by a factor of 5 - 7% [14] by including the 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 Joule-Thomson (JT) effect is a thermodynamic process that occurs when a fluid expands from high pressure to low pressure at constant enthalpy (an isenthalpic process). Such a process can be approximated in the real world by expanding a fluid from high pressure to low pressure across a valve.

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 ].

Studied by the man who gives it its name, Willian Thomson in 1851, where it was first predicted on paper and then empirically demonstrated, we talk about an effect that has serious connotations for the PC industry and just a couple of problems to solve. 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. Consider a copper bar AB heated in the middle at the point C and current flowing as shown in Fig: a.

For the case of the Joule-Thomson effect, both cooling and heating are produced.
