Backends in CoolProp
|
|
********************
|
|
|
|
AbstractState
|
|
-------------
|
|
The :cpapi:`AbstractState` defines an interface between CoolProp and the rest of the world. The public methods like :cpapi:`AbstractState::rhomolar` are meant to be called by other code, while the protected functions like :cpapi:`AbstractState::calc_rhomolar` are meant to be implemented by the other backends.

|
|
|
Derived Backends
|
|
----------------
|
|
|
|
The backends in CoolProp provide the implementation of the protocol defined by the abstract base class. There are a few primary backends:
|
|
|
|
* :cpapi:`HelmholtzEOSMixtureBackend` : This backend is the backend that provides properties using the CoolProp code.
|
|
* :cpapi:`IncompressibleBackend` : This backend provided the thermophysical properties for incompressible pure fluids, incompressible mixtures, and brines
|
|
* :cpapi:`REFPROPMixtureBackend` : This backend provides a clean interface between CoolProp and REFPROP
|
