Cooling through ethanol throttling expansion
Thread Content
Throttling Expansion: A process in which a fluid (gas or liquid) at higher pressure expands adiabatically toward a lower pressure through a porous plug (or throttle valve). When μJ.T is positive, the gas cools down; otherwise, it heats up. At atmospheric pressure, in the Joule-Thomson effect, helium and hydrogen are generally gases that cause a temperature increase, while most other gases result in a temperature decrease. For ideal gases, the Joule-Thomson coefficient is zero; thus, they neither experience a temperature increase nor a decrease in the Joule-Thomson effect. Where can I find information on how the temperature changes after liquid throttling expansion? Does ethanol cool down or heat up after throttling expansion? I’m asking for help and guidance; thank you
It should be an increase in temperature; it is recommended to study the Carnot principle and the reverse Carnot principle
I hope someone upstairs can explain it in detail. Thank you
