WebLinde's Method. This method makes use of Joule Thomson effect and is used to liquify air or any other gas. Pure air or any gas is first compressed to about 200 atmospheres and is allowed to enter the innertube of the concentric pipes as shown in Fig.10.8. The valve v of jet J is then opened and the gas is allowed to expand suddenly into the ... WebThe Thomson effect depends both on the temperature gradient and charge current across the material. Unlike the Peltier and Seebeck effects, the Thomson effect does not require the presence of two materials—it can also occur in a homogenous slab of one substance.

Web14 Jun 2024 · At any given pressure and temperature, the Joule-Thomson coefficient, μJT, is the slope of this curve. We can also express μJT as a function of the heat capacity, CP, and the coefficient of thermal expansion, α, where α = V − 1(∂V / ∂T)P. We begin by expressing d¯ H as a function of temperature and pressure: d¯ H = (∂¯ H ∂T)PdT ...

Web7 Oct 2024 · The Joule-Thomson Effect. Any time a gas expands, it requires energy to do so. So, as a gas transitions from a high-pressure state to a low-pressure state, it consumes energy from the surrounding area to do so. The phenomenon of a gas drawing its energy from the surrounding air is known as the Joule-Thomson effect. WebThe thermodynamic basis of the Joule-Thomson effect is best understood by considering a discrete packet of gas upstream of a restriction. In order for the packet of gas to pass through the restriction the upstream gas must do some work to push the packet through. This work is equal to volume of the packet times the upstream pressure:

WebThomson effect. Thomson showed that if two points in a conductor are at different temperatures, the density of electrons at these points will differ and as a result the potential difference is created between these points.
