Multiphase Mixtures#

MultiPhase()
MultiPhase(phases::AbstractVector{<:Pair{Solution,<:Real}})

A mixture of one or more phases. Construct empty and add phases with add_phase! followed by init!, or pass a vector of solution => moles pairs to add and initialize in one step.

gas = Solution("gri30.yaml")
mix = MultiPhase([gas => 1.0])
set_temperature!(mix, 1200.0); set_pressure!(mix, one_atm)
equilibrate!(mix, "TP")
add_phase!(mp::MultiPhase, solution::Solution, moles::Real)

Add solution to the mixture with the given number of moles. Call init! after all phases have been added.

init!(mp::MultiPhase)

Finalize the mixture after all phases have been added. Required before any property or equilibrium calculation.

update_phases!(mp::MultiPhase)

Synchronize the constituent phase objects with the mixture’s current state.

n_phases(mp::MultiPhase)

Number of phases in the mixture.

set_temperature!(mp::MultiPhase, T::Real)

Set the mixture temperature [K].

set_pressure!(mp::MultiPhase, P::Real)

Set the mixture pressure [Pa].

charge(mp::MultiPhase)

Total electric charge [C/mol] of the mixture.

enthalpy(mp::MultiPhase)

Total enthalpy [J].

entropy(mp::MultiPhase)

Total entropy [J/K].

gibbs(mp::MultiPhase)

Total Gibbs free energy [J].

volume(mp::MultiPhase)

Total volume [m^3].

phase_moles(mp::MultiPhase, n::Integer)

Number of moles in phase n (1-based).

set_phase_moles!(mp::MultiPhase, n::Integer, moles::Real)

Set the number of moles in phase n (1-based).

species_moles(mp::MultiPhase, k::Integer)

Moles of global species k (1-based).

element_moles(mp::MultiPhase, m::Integer)

Moles of element m (1-based).

mole_fraction(mp::MultiPhase, k::Integer)

Mole fraction of global species k (1-based).

set_moles!(mp::MultiPhase, moles)

Set the moles of all global species from a numeric vector, or from a composition string (e.g. "CH4:1, O2:2").
