11. The principle of operation is similar to the near isentropic Brayton cycle of a turboexpander. 12. Examples include barotropic layers of the oceans, an isothermal ideal gas or an isentropic ideal gas. 13. The ratio relation allows one to express the isentropic compressibility in terms of the heat capacity ratio. 14. This means that a homentropic flow is necessarily isentropic , but an isentropic flow need not be homentropic. 15. This means that a homentropic flow is necessarily isentropic, but an isentropic flow need not be homentropic. 16. Its operation relies on the different properties of gases flowing at isentropic ( gas entropy is nearly constant ). 17. It is referred to, speaking more strictly, as an isentropic process with a fixed number of particles. 18. A version called the Single Layer Isentropic Model of Chemistry And Transport ( SLIMCAT ) was developed in 1995. 19. For example, a steam turbine is not isentropic , as friction, choke and shock processes produce entropy. 20. For reversible processes, an isentropic transformation is carried out by thermally " insulating " the system from its surroundings.
