With an air pressure of only 40 bar ( 4 MPa ), Claude achieved an almost isentropic expansion resulting in a lower temperature than had before been possible.

Under a perfect gas model there is an elegant set of equations for determining thermodynamic state along a constant entropy stream line called the " isentropic chain ".
43.
Taking into account the established assumptions, in a system where the downstream properties are becoming subsonic : the upstream and downstream flow properties of the fluid are considered isentropic.
44.
The angles in this pattern are not intrinsic properties of merely water : Any isentropic and incompressible liquid with low viscosity will exhibit the " same " phenomenon.
45.
Weak shocks are isentropic and that the isentrope represents the path through which the material is loaded from the initial to final states by a compression wave with converging characteristics.
46.
Since neither the compression nor the expansion can be truly isentropic, losses through the compressor and the expander represent sources of inescapable working power output of a Brayton system.
47.
The cavern space can be easily insulated, compressed adiabatically with little temperature change ( approaching a reversible isothermal system ) and heat loss ( approaching an isentropic system ).
48.
The refrigerant liquid flows through the turboexpander where it is vaporized and the vapor undergoes an isentropic expansion which results in a low-temperature mixture of vapor and liquid.
49.
The numerical method is efficient in simulating real-time dynamics or calculations of isentropic interpolations between a target Hamiltonian and a Hamiltonian with an already-known ground state.
50.
Note that energy "'can "'be exchanged with the flow in an isentropic transformation, as long as it doesn't happen as heat exchange.
