Liquificarion is a phase change and air is deviating strongly from ideal in the liquificarion process. The expansion process is also not cyclic so Carnot doesn't apply.
- aurizon 7y agoIt is quite hard to attain Carnot irrevers sability, so the losses are indeed worse than the Carnot case.
- dredmorbius 7y agoBoiling of LN2 results in a gas, which would then be used to drive a conventional turbine, with a "hot" (comparatively) and cold end, hence, a Carnot process. Condensation of the (now gaseous) nitrogen within the turbine would all but certainly result in significant cavitation effects, as well as create a very low-pressure zone on the exhaust side of the turbine, which would probably not be conducive to normal operation. Heat of vapourisation is not free, and would have to be supplied, somehow.
