Class to read the source term modelling the presence of a bundle of tubes in a flow. Cf=A Re-B.

Inherits from: spec_pdcr_base

Class to define the pressure loss in the direction of the tube bundle.

Parameters:

dir (type: string into ['x', 'y', 'z']) Direction.
dd (type: float) Tube bundle hydraulic diameter value. This value is expressed in m.
ch_a (type: string into ['a', 'cf']) Keyword to be used to set law coefficient values for the coefficient of regular pressure losses.
a (type: float) Value of a law coefficient for regular pressure losses.
[ch_b] (type: string into ['b']) Keyword to be used to set law coefficient values for regular pressure losses.
[b] (type: float) Value of a law coefficient for regular pressure losses.

Inherits from: spec_pdcr_base

Class to define the pressure loss in the direction perpendicular to the tube bundle.

Parameters:

dir (type: string into ['x', 'y', 'z']) Direction.
dd (type: float) Value of the tube bundle step.
chaine_d (type: string into ['d']) Keyword to be used to set the value of the tube external diameter.
d (type: float) Value of the tube external diameter.
ch_a (type: string into ['a', 'cf']) Keyword to be used to set law coefficient values for the coefficient of regular pressure losses.
a (type: float) Value of a law coefficient for regular pressure losses.
[ch_b] (type: string into ['b']) Keyword to be used to set law coefficient values for regular pressure losses.
[b] (type: float) Value of a law coefficient for regular pressure losses.
