Synonym: Throttling Temperature effect = Joule–Thomson effect
Temperature change of a fluid (except ideal gas) when it is forced through a valve or percolating through porous medium while keeping it insulated so that no heat is exchanged with the environment (that is, at constant enthalpy LaTeX Math Inline |
