useEosProperties

private boolean useEosProperties

Flag to control whether EOS-based properties should be used instead of literature-based values.

When true, thermodynamic properties (density, entropy, enthalpy, heat capacities) are calculated using the underlying equation of state (SRK EOS). This is useful for Pedersen's approach where asphaltene is modeled as a heavy liquid phase with EOS-calculable properties.

When false (default), solid-specific literature values are used for properties like density (e.g., 1150 kg/m³ for asphaltene), and residual properties return 0 as is typical for solids.

getEnthalpy

public double getEnthalpy()

method to return enthalpy of a phase in unit Joule.

Specified by:

getEnthalpy in interface PhaseInterface

Overrides:

getEnthalpy in class Phase

Returns:

isAsphaltenePhase

public boolean isAsphaltenePhase()

Checks if this solid phase is predominantly asphaltene (> 50 mol% asphaltene).

Returns:

true if phase contains majority asphaltene

updatePhaseTypeForAsphaltene

public void updatePhaseTypeForAsphaltene()

Updates the phase type to ASPHALTENE if this phase is predominantly asphaltene. Call this after flash calculations to properly identify asphaltene-rich solid phases.

getAsphaltenePhaseAltDensity

private double getAsphaltenePhaseAltDensity()

Get asphaltene density based on literature values. Asphaltene density is typically 1100-1200 kg/m³.

Returns:

asphaltene density in kg/m3

isUseEosProperties

public boolean isUseEosProperties()

Check if EOS-based properties are used for this solid phase.

Returns:

true if EOS properties are used, false if literature-based values are used

setUseEosProperties

public void setUseEosProperties(boolean useEosProperties)

Set whether to use EOS-based properties for this solid phase.

When enabled, thermodynamic properties (density, entropy, enthalpy, heat capacities) are calculated using the underlying equation of state. This is useful for Pedersen's approach where asphaltene behaves more like a heavy liquid phase.

Parameters:

useEosProperties - true to use EOS properties, false to use literature-based values

getSresTP

public double getSresTP()

getSresTP.

For solids, the residual entropy is approximated as zero since there is no PVT contribution for incompressible solids at their reference state. When isUseEosProperties() is true, EOS-based calculation is used instead.

Specified by:

getSresTP in interface PhaseInterface

Overrides:

getSresTP in class PhaseEos

Returns:

a double

getHresTP

public double getHresTP()

getHresTP.

For solids, the residual enthalpy is approximated as zero since the PVT contribution for incompressible solids is negligible. When isUseEosProperties() is true, EOS-based calculation is used instead.

Specified by:

getHresTP in interface PhaseInterface

Overrides:

getHresTP in class PhaseEos

Returns:

a double

getCpres

public double getCpres()

getCpres.

For solids, the residual heat capacity at constant pressure is approximated as zero. When isUseEosProperties() is true, EOS-based calculation is used instead.

Specified by:

getCpres in interface PhaseInterface

Overrides:

getCpres in class PhaseEos

Returns:

a double

getCvres

public double getCvres()

getCvres.

For solids, the residual heat capacity at constant volume is approximated as zero. When isUseEosProperties() is true, EOS-based calculation is used instead.

Overrides:

getCvres in class PhaseEos

Returns:

a double

getCp

public double getCp()

method to return specific heat capacity (Cp).

For solids, the heat capacity is taken as the sum of component heat capacities.

Specified by:

getCp in interface PhaseInterface

Overrides:

getCp in class Phase

Returns:

Cp in unit J/K

getCv

public double getCv()

method to return specific heat capacity (Cv).

For solids, Cv is approximately equal to Cp since solids are nearly incompressible.

Specified by:

getCv in interface PhaseInterface

Overrides:

getCv in class Phase

Returns:

Cv in unit J/K

getSoundSpeed

public double getSoundSpeed()

Get the speed of sound of a phase note: implemented in phaseEos.

Speed of sound in solids is typically 1500-4000 m/s for organic solids.

Specified by:

getSoundSpeed in interface PhaseInterface

Overrides:

getSoundSpeed in class PhaseEos

Returns:

speed of sound in m/s

getJouleThomsonCoefficient

public double getJouleThomsonCoefficient()

Get the Joule Thomson Coefficient of a phase.

For solids, the Joule-Thomson coefficient is typically very small since solids are nearly incompressible. When isUseEosProperties() is true, EOS-based calculation is used instead.

Specified by:

getJouleThomsonCoefficient in interface PhaseInterface

Overrides:

getJouleThomsonCoefficient in class PhaseEos

Returns:

Joule Thomson coefficient in K/bar

getDensity

public double getDensity()

Get density of a phase note: does not use Peneloux volume correction.

For asphaltene phases, returns a realistic density based on literature values. For other solid phases, uses the standard EOS-based calculation. When isUseEosProperties() is true, always uses EOS-based calculation regardless of phase type.

Specified by:

getDensity in interface PhaseInterface

Overrides:

getDensity in class Phase

Returns:

density with unit kg/m3
