gaspype.fluid_system#

class gaspype.fluid_system(species, t_min=250, t_max=2000)#

Bases: object

A class to represent a fluid_system defined by a set of selected species.

species_names#

List of selected species in the fluid_system

array_molar_mass#

Array of the molar masses of the species in the fluid_system

array_element_composition#

Array of the element composition of the species in the fluid_system. Dimension is: (number of species, number of elements)

array_atomic_mass#

Array of the atomic masses of the elements in the fluid_system

Instantiates a fluid_system.

Parameters:

species (list[str] | str) – List of species names to be available in the constructed fluid_system (as list of strings or a comma separated string)
t_min (int) – Lower bound of the required temperature range in Kelvin
t_max (int) – Upper bound of the required temperature range in Kelvin

get_species_cp(t)#

Parameters:: t (float | ndarray[tuple[Any, ...], dtype[float64]]) – Temperature in Kelvin (can be an array)
Return type:: ndarray[tuple[Any, ...], dtype[float64]]
Returns:: Array with the heat capacities of each specie in J/mol/K

get_species_g_rt(t)#
