Hydrogen joule thomson effect

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 … Meer weergeven The effect is named after James Prescott Joule and William Thomson, 1st Baron Kelvin, who discovered it in 1852. It followed upon earlier work by Joule on Joule expansion, in which a gas undergoes … Meer weergeven There are two factors that can change the temperature of a fluid during an adiabatic expansion: a change in internal energy or the … Meer weergeven In practice, the Joule–Thomson effect is achieved by allowing the gas to expand through a throttling device (usually a valve) which must … Meer weergeven A very convenient way to get a quantitative understanding of the throttling process is by using diagrams such as h-T diagrams, h-P diagrams, and others. Commonly used are the so-called T-s diagrams. Figure 2 shows the T-s diagram of nitrogen … Meer weergeven The adiabatic (no heat exchanged) expansion of a gas may be carried out in a number of ways.
