Enum Class PhaseModifiedFurstElectrolyteEos.DielectricMixingRule

java.lang.Object

java.lang.Enum<PhaseModifiedFurstElectrolyteEos.DielectricMixingRule>

neqsim.thermo.phase.PhaseModifiedFurstElectrolyteEos.DielectricMixingRule

All Implemented Interfaces:

Serializable, Comparable<PhaseModifiedFurstElectrolyteEos.DielectricMixingRule>, Constable

Enclosing class:

PhaseModifiedFurstElectrolyteEos

public static enum PhaseModifiedFurstElectrolyteEos.DielectricMixingRule
extends Enum<PhaseModifiedFurstElectrolyteEos.DielectricMixingRule>

Enum for selecting dielectric constant mixing rules for mixed solvents.

Warning: Only MOLAR_AVERAGE is fully thermodynamically consistent. VOLUME_AVERAGE and LOOYENGA provide correct dielectric constant values but have incomplete composition derivatives (dε/dn), which may cause issues with fugacity coefficient calculations and phase equilibrium. Use MOLAR_AVERAGE (default) for rigorous thermodynamic calculations.

Enum Constant Details

MOLAR_AVERAGE

public static final PhaseModifiedFurstElectrolyteEos.DielectricMixingRule MOLAR_AVERAGE

Molar average: eps_mix = sum(x_i * eps_i). Standard NeqSim approach. Fully consistent.

VOLUME_AVERAGE

public static final PhaseModifiedFurstElectrolyteEos.DielectricMixingRule VOLUME_AVERAGE

Volume average: eps_mix = sum(phi_i * eps_i). Better for water-glycol mixtures (2.4% avg error vs 4.2% for molar). Warning: Composition derivatives not implemented - use for property estimation only, not phase equilibrium.

LOOYENGA

public static final PhaseModifiedFurstElectrolyteEos.DielectricMixingRule LOOYENGA

Looyenga: eps_mix^(1/3) = sum(phi_i * eps_i^(1/3)). Theoretical basis for polar mixtures. Warning: Composition derivatives not implemented - use for property estimation only, not phase equilibrium.

Method Details

values

public static PhaseModifiedFurstElectrolyteEos.DielectricMixingRule[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static PhaseModifiedFurstElectrolyteEos.DielectricMixingRule valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
