Joule–thomson effect hydrogen
NettetThe expansion process of real hydrogen gas raises the static temperature of the gas, due to the Joule-Thomson effect (J-T effect). There is deviation between ideal hydrogen gas and real hydrogen gas under the condition of high … Nettet1. sep. 2007 · Reverse Joule–Thomson effect When a compressed gas is vented to atmosphere through a nozzle, the gas expands. If it is below the Joule–Thomson inversion temperature, then the gas cools on expansion. The inversion temperature for air is about 325 °C, so air at ambient temperature and above atmospheric pressure will …
