fuellib.utility

Utility functions for mixture calculations and droplet properties.

Functions

droplet_mass(fuel, r, Yi, T)	Calculate the mass of each compound in the fuel provided the radius of the droplet.
droplet_volume(r)	Calculate spherical volume of a droplet given the radius.
mixing_rule(var_n, X[, pseudo_prop])	Mixing rules for computing mixture properties.

fuellib.utility.droplet_mass(fuel, r, Yi, T)

Calculate the mass of each compound in the fuel provided the radius of the droplet.

Parameters:

• fuel (fuel object) – An instance of the fuel class.

• r (float) – Radius of the droplet in meters.

• Yi (np.ndarray) – Mass fractions of each compound.

• T (float) – Droplet temperature in Kelvin.

Returns:

Mass of each compound in droplet in kg.

Return type:

np.ndarray

fuellib.utility.droplet_volume(r)

Calculate spherical volume of a droplet given the radius.

Parameters:

r (float) – Radius of the droplet in meters.

Returns:

Spherical volume of droplet in cubic meters.

Return type:

float

fuellib.utility.mixing_rule(var_n, X, pseudo_prop='arithmetic')

Mixing rules for computing mixture properties.

Parameters:

• var_n (np.ndarray) – Individual compound properties.

• X (np.ndarray) – Mole fractions of the compounds.

• pseudo_prop (str, optional) – Type of mean (“arithmetic” or “geometric”).

Returns:

Mixture property value.

Return type:

float
