lib.corriente module

Module with stream definition:

• Corriente: Stream general class model

• PsyStream: Stream specified as psychrometric state

lib.corriente.translate(context: str, sourceText: str, disambiguation: str = None, n: int = -1) → str

class lib.corriente.Corriente(**kwargs)

Bases: Entity

Class to model a stream object Parameters:

-T: temperature, Kelvin -P: Pressure, Pa -x: quality

-caudalMasico: mass flow in kg/s (solid component excluded) -caudalMolar: molar flow in kmol/s (solid component excluded) -caudalVolumetrico: volumetric flow in m3/s -caudalUnitarioMolar: Array with molar flows for each component -caudalUnitarioMasico: Array with mass flows for each component -fraccionMolar: Array with molar fractions for each component -fraccionMasica: Array with mass fractions for each component -mezcla: instance of class Mezcla to define all mixture variables

-solido: Instance of class Solid to define all solid variables -caudalSolido: mass flow, in kg/h for solids component, array for each

solid component

-diametroMedio: mean diameter for particules, in micrometer -distribucion_fraccion: Array with mass fraccion of solid particle

distribution

-distribucion_diametro: Array with particle diameter of solid particle

distribution, in micrometer

-notas: Description text for stream

Aditional parameter for define a corriente with different properties than the project config, components for debug, thermodynamic method for add per stream configuration:

-ids: Array with index of components -solids: Array with index of solids components

-K: Name of method for K values calculation, ej: “SRK”, “Lee-Kesler” -alfa: Name of method for alpha calculation, available only for some K

methods

-mix: Mixing rule for calculate mix properties -H: Name of method for enthalpy calculation, ej: “SRK”, “Lee-Kesler” -Cp_ideal: Bool to choose method for ideal cp:

0 - Ideal parameters 1 - DIPPR parameters

-MEoS: Use meos equation if is available -iapws: Use iapws97 standard for water -GERG: Use GERG-2008 equation if is available -freesteam: Use freesteam external library for water -coolProp: Use coolProp external library if is available -refprop: Use refProp external library if is available
