Thomson effects
WebPrinciple. A stream of gas is fed to a throttling point, where the gas ( CO2 or N2) undergoes adiabatic expansion. The differences in temperature established between the two sides of the throttle point are measured at various pressures and the Joule-Thomson coefficients of the gases in question are calculated.

WebMar 19, 2024 · The Thomson effect is considered as a heat source/sink, commonly, which is added to the Joule-heating. Some attempt has been to consider the Thomson effect, but … The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa via a thermocouple. A thermoelectric device creates a voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, heat is transferred from one side to the other, creating a temperature difference. At the atomic scale, an applied tempe…
