"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 … Se mer 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 free … Se mer There are two factors that can change the temperature of a fluid during an adiabatic expansion: a change in internal energy or the conversion between potential and kinetic internal energy. Temperature is the measure of thermal kinetic energy (energy associated with … Se mer In practice, the Joule–Thomson effect is achieved by allowing the gas to expand through a throttling device (usually a valve) which must be very … Se mer 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 … Se mer The adiabatic (no heat exchanged) expansion of a gas may be carried out in a number of ways. The change in temperature … Se mer The rate of change of temperature $${\displaystyle T}$$ with respect to pressure $${\displaystyle P}$$ in a Joule–Thomson process (that is, at constant enthalpy $${\displaystyle H}$$) is the Joule–Thomson (Kelvin) coefficient Se mer In thermodynamics so-called "specific" quantities are quantities per unit mass (kg) and are denoted by lower-case characters. So h, u, and v are the specific enthalpy, specific internal … Se mer " - Joule thomson cryostat
