Detailed Description

Code for all the binary pairs in the mixture.

This file contains flash routines in which the state is unknown, and a solver of some kind must be used to obtain temperature and density, the two state variables upon which the equation of state is based.

This file contains derivatives needed in the mixture model. The derivatives are quite nasty, and there are a lot of them, so they are put in this file for cleanness. The MixtureDerivatives class is a friend class of the HelmholtzEOSMixtureBackend, so it can access all the private members of the HelmholtzEOSMixtureBackend class

This includes both binary pair information for the reducing functions as well as the departure functions for the given binary pair.

typedef std::vector<std::vector<double> > CoolProp::mat

This class implements bicubic interpolation, as very clearly laid out by the page on wikipedia: http://en.wikipedia.org/wiki/Bicubic_interpolation.

Essentially you have an already-inverted matrix that you need to multiply

\[ A^{-1} = \left[ \begin{array}{*{16}c} 1 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 \\ 0 & 0 & 0 & 0 & 1 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 \\ -3 & 3 & 0 & 0 & -2 & -1 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 \\ 2 & -2 & 0 & 0 & 1 & 1 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 \\ 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 1 & 0 & 0 & 0 & 0 & 0 & 0 & 0 \\ 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 1 & 0 & 0 & 0 \\ 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & -3 & 3 & 0 & 0 & -2 & -1 & 0 & 0 \\ 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 2 & -2 & 0 & 0 & 1 & 1 & 0 & 0 \\ -3 & 0 & 3 & 0 & 0 & 0 & 0 & 0 & -2 & 0 & -1 & 0 & 0 & 0 & 0 & 0 \\ 0 & 0 & 0 & 0 & -3 & 0 & 3 & 0 & 0 & 0 & 0 & 0 & -2 & 0 & -1 & 0 \\ 9 & -9 & -9 & 9 & 6 & 3 & -6 & -3 & 6 & -6 & 3 & -3 & 4 & 2 & 2 & 1 \\ -6 & 6 & 6 & -6 & -3 & -3 & 3 & 3 & -4 & 4 & -2 & 2 & -2 & -2 & -1 & -1 \\ 2 & 0 & -2 & 0 & 0 & 0 & 0 & 0 & 1 & 0 & 1 & 0 & 0 & 0 & 0 & 0 \\ 0 & 0 & 0 & 0 & 2 & 0 & -2 & 0 & 0 & 0 & 0 & 0 & 1 & 0 & 1 & 0 \\ -6 & 6 & 6 & -6 & -4 & -2 & 4 & 2 & -3 & 3 & -3 & 3 & -2 & -1 & -2 & -1 \\ 4 & -4 & -4 & 4 & 2 & 2 & -2 & -2 & 2 & -2 & 2 & -2 & 1 & 1 & 1 & 1 \end{array} \right] \]

\[ x = \frac{h-h_i}{h_{i+1}-h_i} \]

\[ \frac{\partial x}{\partial h} = \frac{1}{h_{i+1}-h_i} \]

\[ \frac{\partial h}{\partial x} = h_{i+1}-h_i \]

\[ y = \frac{p-p_j}{p_{j+1}-p_j} \]

\[ \frac{\partial y}{\partial p} = \frac{1}{p_{j+1}-p_j} \]

\[ \frac{\partial p}{\partial y} = p_{j+1}-p_j \]

In this formulation of the Multi-Dimensional Newton-Raphson solver the Jacobian matrix is known. Therefore, the dx vector can be obtained from

for a given value of x. The pointer to the class FuncWrapperND that is passed in must implement the call() and Jacobian() functions, each of which take the vector x. The data is managed using std::vector<double> vectors

Parameters
fA pointer to an subclass of the FuncWrapperND class that implements the call() and Jacobian() functions
x0The initial guess value for the solution
tolThe root-sum-square of the errors from each of the components
maxiterThe maximum number of iterations
errstringA string with the returned error. If the length of errstring is zero, no errors were found
wA relaxation multiplier on the step size, multiplying the normal step size
Returns
If no errors are found, the solution. Otherwise, _HUGE, the value for infinity
