Joule thomson heater
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 … 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. 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 well insulated to prevent any heat transfer to or from the gas. No external work is extracted from the gas during the … 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 experienced by the gas during expansion depends not only on the initial and final pressure, but also on the manner in which the … 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 Se mer NettetThe Joule–Thomson coefficient ηJT is defined as the variation of temperature with pressure at constant enthalpy: (2.33) It can be derived from volumetric properties: (2.34) The Joule–Thomson coefficient of an ideal gas is zero. In real gases, the Joule–Thomson coefficient is different from zero and depends on pressure and …
