Isentropic process of Reissner-Nordström black holes: A possible excess of the entropy bound via a nonperturbative channel

We study the implications of an isentropic processes applied to a Reissner-Nordström black hole. This process is possible if a black hole absorbs a particle with a specific ratio of energy and charge.

Isentropic process - lookup with P,S inputs

I'm trying to model an isentropic process with air, but CP.Props() fails when looking up enthalpy given inputs P and S. According to the docs, this is a valid lookup combination, and it does give ...

“HumidAirProps” violates the first law of thermodynamic for isentropic process

For an isentropic compression process, the relation dh=vdp can be found in any text book. When I calculate the compression work for high pressure humid air, the enthalpy obtained with function ...
