Constructor Details

PhaseSrkCPAs

public PhaseSrkCPAs()

Constructor for PhaseSrkCPAs.

Method Details

clone

public PhaseSrkCPAs clone()

clone.

Specified by:

clone in interface PhaseInterface

Overrides:

clone in class PhaseSrkCPA

Returns:

a PhaseInterface object

addComponent

public void addComponent(String name,
 double moles,
 double molesInPhase,
 int compNumber)

Add component to component array and update moles variables.

Specified by:

addComponent in interface PhaseInterface

Overrides:

addComponent in class PhaseSrkCPA

Parameters:

name - Name of component.

moles - Total number of moles of component.

molesInPhase - Number of moles in phase.

compNumber - Index number of component in phase object component array.

calc_g

public double calc_g()

Calculate radial distribution function g at contact using simplified Carnahan-Starling.

g = (2 - b/4V) / (2 * (1 - b/4V)³)

This formula is the same for all cubic EOS (SRK, PR, UMR) since it depends only on the co-volume parameter b, not on the attraction parameter a.

Returns:

g value

calc_lngV

public double calc_lngV()

Calculate first volume derivative of ln(g).

d(ln g)/dV

Returns:

d(ln g)/dV

calc_lngVV

public double calc_lngVV()

Calculate second volume derivative of ln(g).

d²(ln g)/dV²

Returns:

d²(ln g)/dV²

calc_lngVVV

public double calc_lngVVV()

Calculate third volume derivative of ln(g).

d³(ln g)/dV³

Returns:

d³(ln g)/dV³
