Importance of joule thomson effect
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 expansion in a vacuum and the temperature is unchanged, if the gas is ideal. Zobacz więcej 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 … Zobacz więcej There are two factors that can change the temperature of a fluid during an adiabatic expansion: a change in internal energy or the conversion … Zobacz więcej In practice, the Joule–Thomson effect is achieved by allowing the gas to expand through a throttling device (usually a valve) which must be … Zobacz więcej A very convenient way to get a quantitative understanding of the throttling process is by using diagrams such as h-T diagrams, h-P … Zobacz więcej The adiabatic (no heat exchanged) expansion of a gas may be carried out in a number of ways. The change in temperature … Zobacz więcej The rate of change of temperature $${\displaystyle T}$$ with respect to pressure $${\displaystyle P}$$ in a Joule–Thomson … Zobacz więcej 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 … Zobacz więcej WitrynaValues for the Joule–Thomson coefficient are listed in Table 2.8 for H 2 O. Although the Joule–Thomson coefficient is not a thermodynamic property for itself, the effect is important for practical purposes and values for the Joule–Thomson coefficient help to realize the changes occurring during processes.
