Detailed Description
The mother of all state classes.
This class provides the basic properties based on interrelations of the properties, their derivatives and the Helmholtz energy terms. It does not provide the mechanism to update the values. This has to be implemented in a subclass. Most functions are defined as virtual functions allowing us redefine them later, for example to implement the TTSE technique. The functions defined here are always used as a fall-back.
This base class does not perform any checks on the two-phase conditions and alike. Most of the functions defined here only apply to compressible single state substances. Make sure you are aware of all the assumptions we made when using this class.

Definition at line 716 of file AbstractState.h.
◆ factory() [2/2]
|
static |
A factory function to return a pointer to a new-allocated instance of one of the backends.
- Parameters
-
backend The backend in use, "HEOS", "REFPROP", etc. fluid_names A vector of strings of the fluid names
- Returns
- A pointer to the instance generated
Several backends are possible:
- "?" : The backend is unknown, we will parse the fluid string to determine the backend to be used. Probably will use HEOS backend (see below)
- "HEOS" : The Helmholtz Equation of State backend for use with pure and pseudo-pure fluids, and mixtures, all of which are based on multi-parameter Helmholtz Energy equations of state. The fluid part of the string should then either be
- A pure or pseudo-pure fluid name (eg. "PROPANE" or "R410A"), yielding a HelmholtzEOSBackend instance.
- A string that encodes the components of the mixture with a "&" between them (e.g. "R32&R125"), yielding a HelmholtzEOSMixtureBackend instance.
- "REFPROP" : The REFPROP backend will be used. The fluid part of the string should then either be
- A pure or pseudo-pure fluid name (eg. "PROPANE" or "R410A"), yielding a REFPROPBackend instance.
- A string that encodes the components of the mixture with a "&" between them (e.g. "R32&R125"), yielding a REFPROPMixtureBackend instance.
- "INCOMP": The incompressible backend will be used
- "TTSE&XXXX": The TTSE backend will be used, and the tables will be generated using the XXXX backend where XXXX is one of the base backends("HEOS", "REFPROP", etc. )
- "BICUBIC&XXXX": The Bicubic backend will be used, and the tables will be generated using the XXXX backend where XXXX is one of the base backends("HEOS", "REFPROP", etc. )
Very Important!! : Use a smart pointer to manage the pointer returned. In older versions of C++, you can use std::tr1::smart_ptr. In C++2011 you can use std::shared_ptr

◆ first_saturation_deriv()

Implementing the algorithms and ideas of: Matthis Thorade, Ali Saadat, "Partial derivatives of thermodynamic state properties for dynamic simulation", Environmental Earth Sciences, December 2013, Volume 70, Issue 8, pp 3497-3503
Basically the idea is that the p-T derivative is given by Clapeyron relations:
\[ \left(\frac{\partial T}{\partial p}\right)_{\sigma} = T\left(\frac{v'' - v'}{h'' - h'}\right)_{\sigma} \]
and then other derivatives can be obtained along the saturation curve from
\[ \left(\frac{\partial y}{\partial p}\right)_{\sigma} = \left(\frac{\partial y}{\partial p}\right)+\left(\frac{\partial y}{\partial T}\right)\left(\frac{\partial T}{\partial p}\right)_{\sigma} \]
\[ \left(\frac{\partial y}{\partial T}\right)_{\sigma} = \left(\frac{\partial y}{\partial T}\right)+\left(\frac{\partial y}{\partial p}\right)\left(\frac{\partial p}{\partial T}\right)_{\sigma} \]
where derivatives without the \( \sigma \) are homogeneous (conventional) derivatives.

|
inline |

and the second derivative can be expressed as
\[ \frac{\partial}{\partial D}\left(\left(\frac{\partial A}{\partial B}\right)_C\right)_E = \frac{\frac{\partial}{\partial T}\left( \left(\frac{\partial A}{\partial B}\right)_C \right)_\rho\left(\frac{\partial E}{\partial \rho}\right)_T-\frac{\partial}{\partial \rho}\left(\left(\frac{\partial A}{\partial B}\right)_C\right)_T\left(\frac{\partial E}{\partial T}\right)_\rho}{\left(\frac{\partial D}{\partial T}\right)_\rho\left(\frac{\partial E}{\partial \rho}\right)_T-\left(\frac{\partial D}{\partial \rho}\right)_T\left(\frac{\partial E}{\partial T}\right)_\rho} \]
which can be expressed in parts as
\[\left(\frac{\partial N}{\partial \rho}\right)_{T} = \left(\frac{\partial A}{\partial T}\right)_\rho\left(\frac{\partial^2 C}{\partial \rho^2}\right)_{T}+\left(\frac{\partial^2 A}{\partial T\partial\rho}\right)\left(\frac{\partial C}{\partial \rho}\right)_{T}-\left(\frac{\partial A}{\partial \rho}\right)_T\left(\frac{\partial^2 C}{\partial T\partial\rho}\right)-\left(\frac{\partial^2 A}{\partial \rho^2}\right)_{T}\left(\frac{\partial C}{\partial T}\right)_\rho\]
\[\left(\frac{\partial D}{\partial \rho}\right)_{T} = \left(\frac{\partial B}{\partial T}\right)_\rho\left(\frac{\partial^2 C}{\partial \rho^2}\right)_{T}+\left(\frac{\partial^2 B}{\partial T\partial\rho}\right)\left(\frac{\partial C}{\partial \rho}\right)_{T}-\left(\frac{\partial B}{\partial \rho}\right)_T\left(\frac{\partial^2 C}{\partial T\partial\rho}\right)-\left(\frac{\partial^2 B}{\partial \rho^2}\right)_{T}\left(\frac{\partial C}{\partial T}\right)_\rho\]
\[\left(\frac{\partial N}{\partial T}\right)_{\rho} = \left(\frac{\partial A}{\partial T}\right)_\rho\left(\frac{\partial^2 C}{\partial \rho\partial T}\right)+\left(\frac{\partial^2 A}{\partial T^2}\right)_\rho\left(\frac{\partial C}{\partial \rho}\right)_{T}-\left(\frac{\partial A}{\partial \rho}\right)_T\left(\frac{\partial^2 C}{\partial T^2}\right)_\rho-\left(\frac{\partial^2 A}{\partial \rho\partial T}\right)\left(\frac{\partial C}{\partial T}\right)_\rho\]

\[\frac{\partial}{\partial \rho}\left( \left(\frac{\partial A}{\partial B}\right)_C \right)_T = \frac{D\left(\frac{\partial N}{\partial \rho}\right)_{T}-N\left(\frac{\partial D}{\partial \rho}\right)_{\tau}}{D^2}\]
\[\frac{\partial}{\partial T}\left( \left(\frac{\partial A}{\partial B}\right)_C \right)_\rho = \frac{D\left(\frac{\partial N}{\partial T}\right)_{\rho}-N\left(\frac{\partial D}{\partial T}\right)_{\rho}}{D^2}\]

◆ second_saturation_deriv()

inline |
The second partial derivative along the saturation curve.
Implementing the algorithms and ideas of: Matthis Thorade, Ali Saadat, "Partial derivatives of thermodynamic state properties for dynamic simulation", Environmental Earth Sciences, December 2013, Volume 70, Issue 8, pp 3497-3503
Like with first_saturation_deriv, we can express the derivative as
\[ \left(\frac{\partial y}{\partial T}\right)_{\sigma} = \left(\frac{\partial y}{\partial T}\right)+\left(\frac{\partial y}{\partial p}\right)\left(\frac{\partial p}{\partial T}\right)_{\sigma} \]
where \( y \) is already a saturation derivative. So you might end up with something like
\[ \left(\frac{\partial \left(\frac{\partial T}{\partial p}\right)_{\sigma}}{\partial T}\right)_{\sigma} = \left(\frac{\partial \left(\frac{\partial T}{\partial p}\right)_{\sigma}}{\partial T}\right)+\left(\frac{\partial \left(\frac{\partial T}{\partial p}\right)_{\sigma}}{\partial p}\right)\left(\frac{\partial p}{\partial T}\right)_{\sigma} \]

\[ tpd(w) = \sum_i w_i(\ln w_i + \ln \phi_i(w) - d_i) \]
with

\[ d_i = \ln f_i(z) - \ln p\]

and the \( \ln p \) cancel, leaving
